RESUMEN
OBJECTIVES: Rheumatoid arthritis (RA) is sometimes complicated by interstitial lung disease (ILD) with a poor prognosis. A single nucleotide variant (SNV) in MUC5B was associated with ILD in European RA patients. However, associations of this SNV were not found in Japanese RA patients, because its frequency in Japanese populations is very low. We investigated the associations of candidate SNVs including the MUC5B variant with ILD in Japanese RA. METHODS: Genotyping of MUC5B rs35705950, MUC2 rs7934606, MAD1L1 rs12699415, and PPFIBP2 rs6578890 in Japanese RA patients was conducted for association analyses. RESULTS: MUC5B rs35705950 was associated with usual interstitial pneumonia (UIP) (p = 0.0039, Pc = 0.0156, odds ratio [OR] 10.66, 95% confidence interval [CI] 2.05-55.37) or ILD (p = 0.0071, Pc = 0.0284, OR 7.33, 95%CI 1.52-35.44) in Japanese RA under the allele model. MUC2 rs7934606 was associated with UIP (p = 0.0072, Pc = 0.0288, OR 29.55, 95%CI 1.52-574.57) or ILD (p = 0.0037, Pc = 0.0148, OR 22.95, 95%CI 1.27-416.13) in RA. Haplotype analyses suggested the primary association of MUC5B rs35705950 with UIP in Japanese RA. No significant association of MAD1L1 rs12699415 or PPFIBP2 rs6578890 with UIP, nonspecific interstitial pneumonia, or ILD in RA was observed. CONCLUSIONS: MUC5B rs35705950 is associated with, and might be involved in the pathogenesis of ILD, especially UIP, in Japanese RA.
RESUMEN
To identify those who might benefit from weight reduction within a large population of obese individuals, Japan Society for the Study of Obesity (JASSO) advocated the concept of "obesity disease." Here we summarize the definition, criteria, and core concepts for the management of obesity disease based on JASSO's latest guideline. JASSO defines obesity as excessive fat storage in adipose tissue associated with a BMI of ≥25 kg/m2. The threshold BMI of obesity is low as compared to Western countries given that Japanese individuals tend to develop obesity-related health disorders at lower BMI. Obesity with a BMI of ≥35 kg/m2 is referred to as "high-degree obesity" as treatment strategies vary based on the degree of obesity. Obesity is diagnosed as "obesity disease" if accompanied by any of the 11 specific obesity-related health disorders that weight reduction can prevent or alleviate, or if it meets the criteria for visceral fat obesity with a visceral fat area of ≥100 cm2. The initial weight reduction goals for high-degree obesity disease range from 5% to 10% of their current body weight, depending on the associated health disorders. That for those with obesity disease who do not qualify as high-degree is 3% or more. If these initial goals are not achieved, intensifying dietary therapy or introducing drug therapy (or both) may be necessary. While surgical treatment is primarily indicated for high-degree obesity disease, it might be appropriate for cases of obesity disease with a BMI <35 kg/m2, depending on the accompanying health disorders. Enhancing the quality of life for individuals with obesity or obesity disease necessitates a broader societal approach, emphasizing the resolution of related stigma.

Interstitial lung disease and airway disease (AD) are often complicated with rheumatoid arthritis (RA) and have a poor prognosis. Several studies reported genetic associations with interstitial lung disease in RA. However, few genetic studies have examined the susceptibility to AD in RA patients. Here, we investigated whether single nucleotide variants susceptible to idiopathic pulmonary fibrosis might be associated with interstitial lung disease or AD in Japanese RA patients. Genotyping of rs2736100 [C/A] in TERT and rs1278769 [G/A] in ATP11A was conducted in 98 RA patients with usual interstitial pneumonia, 120 with nonspecific interstitial pneumonia (NSIP), 227 with AD, and 422 without chronic lung disease using TaqMan assays. An association with AD in RA was found for rs2736100 (p = 0.0043, Pc = 0.0129, odds ratio [OR] 1.40, 95% confidence interval [CI] 1.11-1.77). ATP11A rs1278769 was significantly associated with NSIP in older RA patients (>65 years, p = 0.0010, OR 2.15, 95% CI 1.35-3.40). This study first reported an association of rs2736100 with AD in RA patients and ATP11A rs1278769 with NSIP in older RA patients.

BACKGROUND: This study aimed to assess the long-term effects of tofogliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on atherosclerosis progression and major clinical parameters in patients with type 2 diabetes lacking an apparent history of cardiovascular disease. METHODS: This was a prospective observational 2-year extension study of the "Using TOfogliflozin for Possible better Intervention against Atherosclerosis for type 2 diabetes patients (UTOPIA)" trial, a 2-year randomized intervention study. The primary endpoints represented changes in the carotid intima-media thickness (IMT). Secondary endpoints included brachial-ankle pulse wave velocity (baPWV) and biomarkers for glucose metabolism, lipid metabolism, renal function, and cardiovascular risks. RESULTS: The mean IMT of the common carotid artery (IMT-CCA) significantly decreased in both the tofogliflozin (- 0.067 mm, standard error 0.009, p < 0.001) and conventional treatment groups (- 0.080 mm, SE 0.009, p < 0.001) throughout the follow-up period; however, no significant intergroup differences in the changes (0.013 mm, 95% confidence interval (CI) - 0.012 to 0.037, p = 0.32) were observed in a mixed-effects model for repeated measures. baPWV significantly increased in the conventional treatment group (82.7 ± 210.3 cm/s, p = 0.008) but not in the tofogliflozin group (- 17.5 ± 221.3 cm/s, p = 0.54), resulting in a significant intergroup difference in changes (- 100.2 cm/s, 95% CI - 182.8 to - 17.5, p = 0.018). Compared to the conventional treatment group, tofogliflozin significantly improved the hemoglobin A1c and high-density lipoprotein cholesterol levels, body mass index, abdominal circumference, and systolic blood pressure. The frequencies of total and serious adverse events did not vary significantly between the groups. CONCLUSIONS: Tofogliflozin was not associated with improved inhibition of carotid wall thickening but exerted long-term positive effects on various cardiovascular risk factors and baPWV while showing a good safety profile.

Autoinflammatory diseases are innate immune-mediated inflammatory disorders, unlike autoimmune diseases, which are characterised by abnormalities in adoptive immunity, although autoimmune and autoinflammatory diseases have certain similar clinical features. Familial Mediterranean fever (FMF), the most common monogenic autoinflammatory disease, is associated with mutations in the MEFV gene that encodes pyrin, which results in inflammasome activation and uncontrolled production of interleukin (IL)-1ß. Regular use of colchicine, the primary drug for FMF treatment, prevents febrile attacks and reduces the long-term risk of subsequent complications of amyloid A (AA) amyloidosis. However, a minority of FMF patients develop colchicine resistance, and anti-IL-1ß treatment with canakinumab, which is a genetically modified human IgG subclass type 1 (IgG1) monoclonal antibody specific for human IL-1ß, was beneficial in inhibiting inflammation in such patients. Here, we present a patient with FMF associated with AA amyloidosis, who was treated with canakinumab and demonstrated down-regulated Th17 cells and activated Th17 cells (from 21.4% to 12.8%, and from 1.45% to 0.83%, respectively) in peripheral blood, as shown by immunophenotyping via multicolour flow cytometry and by disease activity and improved laboratory inflammatory surrogate markers-C-reactive protein (CRP) and serum AA protein (SAA). CRP had values within normal limits, but SAA did not (Spearman's rank correlation coefficient; ρ = 0.133). We report that SAA and IL-1ß may differentiate Th17 cells from CD4+-naïve T cells, and we discuss interactions between autoinflammation and autoimmunity as a model based on this case, through modes of action with IL-1ß and SAA. This report is the first demonstrating that an IL-1ß antagonist may reduce Th17 cells in FMF as a therapeutic option.

We have clarified the microbiological characterization of Gambian traditional fermented milk (FM), "Kosam." Two samples of FM were collected at two regions in The Gambia in 2019. The microbiota of these samples was analyzed by culture-dependent methods and Illumina sequencing. The number of lactic acid bacteria (LAB) in FM from Central River Region (CRR) and Lower River Region (LRR) was 8.27 ± 0.08 log CFU/ml and 7.21 ± 0.09 log CFU/ml, respectively. While no coliforms and Escherichia coli were detected in CRR-FM, LRR-FM contained 5.73 ± 0.17 log CFU/ml of coliforms and 4.82 ± 0.13 log CFU/ml of E. coli. The dominant viable LAB in FM from CRR was Lactobacillus delbrueckii, followed by Streptococcus lutetiensis, while that from LRR was Lactococcus lactis. The metagenomic analysis also revealed that these species were dominant in these Gambian traditional FM. Furthermore, it also revealed the possibility of the presence of pathogens such as Klebsiella spp. This study enhanced the knowledge of Gambian FM and contributed to the elucidation of microbial communities.

RESUMEN
An 82 year-old female patient not suffering from diabetes was transported to our hospital with hyperglycemia (HbA1c 8.2%, blood glucose 584 mg/dL) and mildly increased levels of pancreatic exocrine enzymes (amylase 543 IU/L, lipase 59 U/L, elastase-1 479 ng/dL), while there were no findings indicating pancreatitis. Under a diagnosis of new-onset diabetes, she was discharged with oral hypoglycemic agents, as retention of insulin secretion function [blood glucose 117 mg/dL, serum connecting peptide immunoreactivity (CPR) 1.63 ng/mL] with normalization of the enzymes was confirmed following administration. However, at 73 days after the hospitalization, she returned with diabetic ketoacidosis (blood glucose 910 mg/dL, pH in blood gas analysis 7.15, total blood ketone bodies > 7000 µmol/L) with a transient repeated increase of the enzymes (amylase 382 IU/L, lipase 82 U/L, elastase-1 569 ng/dL) and without pancreatitis. Notably, depletion of insulin secretion (6.1 µg/day in urine, 0.36 ng/mL in serum CPR with no response in glucagon-loading test) was revealed, and serum CPR level remained low after discharge. Together with negative findings for islet-related autoantibodies, the patient was diagnosed with acute-onset type 1B diabetes (T1BD). In the present patient with acute-onset T1BD, a mild increase in pancreatic exocrine enzymes was repeatedly observed, which may mimic fulminant type and raise questions for us about the commonly accepted pathophysiology of T1D. These findings may help to clarify issues related to newly developed T1D in elderly individuals.
RESUMEN
INTRODUCTION: Treatment-related quality of life (QOL) is an important aspect of diabetes management. We evaluated the influence of a sodium-glucose cotransporter 2 (SGLT2) inhibitor, tofogliflozin, on treatment-related QOL in Japanese patients with type 2 diabetes mellitus (T2DM). METHODS: This is the prespecified subanalysis study of the "Using TOfogliflozin for Possible better Intervention against Atherosclerosis for type 2 diabetes patients (UTOPIA)" trial. Treatment-related QOL was evaluated at baseline, week 26, week 52, and week 104 after the initiation of the study using the Diabetes Therapy-Related QOL questionnaire (DTR-QOL). Among the 340 patients in the original UTOPIA study, a total of 252 patients (127, tofogliflozin group; 125, conventional treatment group) who completed the DTR-QOL questionnaire at baseline were the study subjects of the current subanalysis. RESULTS: The tofogliflozin and conventional treatment groups exhibited almost comparable baseline clinical characteristics, while the use of antihypertensive drugs and lipid-lowering agents was significantly lower in the tofogliflozin treatment group than in the conventional treatment group. Tofogliflozin treatment increased the total score of DTR-QOL7 from baseline (P < 0.001), while conventional treatment did not change it. There were statistically significant differences in delta change in the total DTR-QOL7 score and DTR-QOL7 Q4, Q5, Q6, and Q7 scores from the baseline to week 104 between the treatment groups. Delta changes in HbA1c (Spearman's correlation coefficient, ρ = - 0.30, P < 0.001), fasting blood glucose (ρ = - 0.16, P = 0.031), BMI (ρ = - 0.19, P = 0.008), and waist circumference (ρ = - 0.17, P = 0.024) at week 104 were negatively associated with delta change in the total QOL7 score. CONCLUSIONS: Our data indicated that tofogliflozin treatment improved treatment-related QOL compared to conventional treatment in Japanese patients with T2DM, in accordance with the improvement of major cardiovascular risk factors.

RESUMEN
Herein, we provide a brief overview of the synthesis and applications of trifluoromethylpyridine (TFMP) and its derivatives in the agrochemical and pharmaceutical industries. Currently, the major use of TFMP derivatives is in the protection of crops from pests. Fluazifop-butyl was the first TFMP derivative introduced to the agrochemical market, and since then, more than 20 new TFMP-containing agrochemicals have acquired ISO common names. Several TFMP derivatives are also used in the pharmaceutical and veterinary industries; five pharmaceutical and two veterinary products containing the TFMP moiety have been granted market approval, and many candidates are currently undergoing clinical trials. The biological activities of TFMP derivatives are thought to be due to the combination of the unique physicochemical properties of the fluorine atom and the unique characteristics of the pyridine moiety. It is expected that many novel applications of TFMP will be discovered in the future.

RESUMEN
CONTEXT: T-cadherin (T-cad) is a glycosylphosphatidylinositol (GPI)-anchored cadherin that mediates adiponectin to induce exosome biogenesis and secretion, protect cardiovascular tissues, promote muscle regeneration, and stimulate therapeutic heart protection by transplanted mesenchymal stem cells. CDH13, the gene locus of T-cad, affects plasma adiponectin levels most strongly, in addition to affecting cardiovascular disease risk and glucose homeostasis. Recently, it has been suggested that T-cad exists in human serum, although the details are still unclear. OBJECTIVE: To validate the existence of T-cad forms in human serum and investigate the association with clinical parameters of type 2 diabetes patients. METHODS: Using newly developed monoclonal antibodies against T-cad, pooled human serum was analyzed, and novel T-cad enzyme-linked immunosorbent assays (ELISAs) were developed. The serum T-cad concentrations of 183 Japanese type 2 diabetes patients were measured in a cross-sectional observational study. The main outcome measure was the existence of soluble T-cad in human serum. RESULTS: There were 3 forms of soluble T-cad: a 130-kDa form with a prodomain, a 100-kDa mature form, and a 30-kDa prodomain in human serum. Using newly developed ELISAs to measure them simultaneously, we found that the 130-kDa form of T-cad positively correlated with plasma adiponectin (râ =â 0.28, Pâ <â .001), although a physiological interaction with adiponectin was not observed in serum. The unique 30-kDa prodomain was associated with several clinical parameters in diabetes patients. CONCLUSION: We identified 3 novel forms of soluble T-cad. Their importance as disease markers and/or biomarkers of adiponectin function and the possible bioactivity of the respective molecules require further investigation.

BACKGROUND: Tofogliflozin, an SGLT2 inhibitor, is associated with favorable metabolic effects, including improved glycemic control and serum lipid profile and decreased body weight, visceral adipose tissue, and blood pressure (BP). This study evaluated the effects of tofogliflozin on the brachial-ankle pulse wave velocity (baPWV) in patients with type 2 diabetes (T2DM) without a history of apparent cardiovascular disease. METHODS: The using tofogliflozin for possible better intervention against atherosclerosis for type 2 diabetes patients (UTOPIA) trial is a prospective, randomized, open-label, multicenter, parallel-group, comparative study. As one of the prespecified secondary outcomes, changes in baPWV over 104 weeks were evaluated in 154 individuals (80 in the tofogliflozin group and 74 in the conventional treatment group) who completed baPWV measurement at baseline. RESULTS: In a mixed-effects model, the progression in the right, left, and mean baPWV over 104 weeks was significantly attenuated with tofogliflozin compared to that with conventional treatment (- 109.3 [- 184.3, - 34.3] (mean change [95% CI] cm/s, p = 0.005; - 98.3 [- 172.6, - 24.1] cm/s, p = 0.010; - 104.7 [- 177.0, - 32.4] cm/s, p = 0.005, respectively). Similar findings were obtained even after adjusting the mixed-effects models for traditional cardiovascular risk factors, including body mass index (BMI), glycated hemoglobin (HbA1c), total cholesterol, high-density lipoprotein (HDL)-cholesterol, triglyceride, systolic blood pressure (SBP), hypertension, smoking, and/or administration of drugs, including hypoglycemic agents, antihypertensive agents, statins, and anti-platelets, at baseline. The findings of the analysis of covariance (ANCOVA) models, which included the treatment group, baseline baPWV, and traditional cardiovascular risk factors, resembled those generated by the mixed-effects models. CONCLUSIONS: Tofogliflozin significantly inhibited the increased baPWV in patients with T2DM without a history of apparent cardiovascular disease, suggesting that tofogliflozin suppressed the progression of arterial stiffness.

BACKGROUND: There have been no reports of treatment effect persistence after long-term sublingual immunotherapy (SLIT) in patients with Japanese cedar (JC) pollinosis. Therefore, we conducted a post-marketing clinical trial to investigate the efficacy, safety, and effect persistence of JC pollen SLIT drops after approximately 3 years of treatment. METHODS: This was an open-label trial of 233 patients with JC pollinosis who were treated with JC pollen SLIT drops for approximately 3 years (2015-2017) and followed-up for an additional 2 years (2018-2019). Efficacy and effect persistence were evaluated using nasal and ocular symptom scores, daily use of rescue medication, and Japanese Rhinoconjunctivitis Quality of Life Questionnaire scores recorded during the JC pollen dispersal season of each year. Safety was evaluated by monitoring adverse events and adverse drug reactions. RESULTS: The mean combined total nasal symptom and medication score (range 0-18) during the peak symptom periods of 2015 through 2019 were 5.47 ± 3.38, 4.52 ± 3.13, 3.58 ± 2.63, 5.28 ± 4.01, and 6.83 ± 4.65, respectively. The percentage of patients who used no rescue medications during the same periods was 64.8%, 75.2%, 80.3%, 63.7%, and 50.3%, respectively. A total of 138 adverse drug reaction incidents were recorded in 73 of the 233 patients (31.3%), of which 134 incidents (97.1%) were mild in severity. CONCLUSIONS: JC pollen SLIT drops demonstrated treatment duration-dependent efficacy with effects that persisted for 2 years after cessation of treatment. The drug had a favorable safety profile over the 5-year study period.

Secondary amyloid A (AA) amyloidosis, which is a disorder of protein conformation and metabolism, is an important serious complication of inflammatory diseases, especially rheumatoid arthritis (RA). AA amyloidosis develops when AA fibrils, which are derived from the acute-phase reactant, serum amyloid AA (SAA) protein, in the circulation, are deposited in organs and cause systemic organ dysfunction. Caplan's syndrome, or rheumatoid pneumoconiosis, is a rare type of lung disease in which individuals suffering from RA develop lung nodules that are associated with occupational exposure to silica and coal dust. Confirmation of diagnosing as Caplan's syndrome requires the patient's occupational history, imaging studies, and serology. A 72-year-old male, working as a tunnel construction worker for 38 years, with RA who had both chronic cardiac and renal dysfunction was referred to our hospital. He received a diagnosis of pneumoconiosis about 20 years ago, after which he was also diagnosed with RA. So far we performed medical English literature searches on the combination of Caplan's syndrome with AA amyloidosis; there were no articles in relation to such association. Although RA is one of the most common underlying diseases that occur with AA amyloidosis, our report here is the first description of a case of Caplan's syndrome associated with AA amyloidosis. In this report, we provide details about this rare disease occurring with AA amyloidosis and discuss on the possible pathogenesis of AA amyloidosis from a genetic point of aetiological view.

BACKGROUND: This study aimed to investigate the preventive effects of tofogliflozin, a selective sodium-glucose cotransporter 2 (SGLT2) inhibitor, on atherosclerosis progression in type 2 diabetes (T2DM) patients without apparent cardiovascular disease (CVD) by monitoring carotid intima-media thickness (IMT). METHODS: This prospective, randomized, open-label, blinded-endpoint, multicenter, parallel-group, comparative study included 340 subjects with T2DM and no history of apparent CVD recruited at 24 clinical units. Subjects were randomly allocated to either the tofogliflozin treatment group (n = 169) or conventional treatment group using drugs other than SGLT2 inhibitors (n = 171). Primary outcomes were changes in mean and maximum common carotid IMT measured by echography during a 104-week treatment period. RESULTS: In a mixed-effects model for repeated measures, the mean IMT of the common carotid artery (mean-IMT-CCA), along with the right and left maximum IMT of the CCA (max-IMT-CCA), significantly declined in both the tofogliflozin (- 0.132 mm, SE 0.007; - 0.163 mm, SE 0.013; - 0.170 mm, SE 0.020, respectively) and the control group (- 0.140 mm, SE 0.006; - 0.190 mm, SE 0.012; - 0.190 mm, SE 0.020, respectively). Furthermore, the tofogliflozin and the conventional treatment group did not significantly differ in the progression of the mean-IMT-CCA (mean change (95% CI) 0.008 (- 0.009, 0.025) mm, P = 0.34), along with the right (mean change (95% CI) 0.027 (- 0.005, 0.059) mm, P = 0.10) and the left max-IMT-CCA (mean change (95% CI) 0.020 (- 0.030, 0.070), P = 0.43). Similar findings were obtained even after adjusting for traditional CV risk factors and/or administration of drugs at baseline. Relative to the control treatment effects, tofogliflozin significantly reduced the HbA1c, blood glucose level, body weight/body mass index, abdominal circumference, and systolic blood pressure, and significantly increased the HDL-C. The total and serious adverse events incidences did not significantly vary between the treatment groups. CONCLUSIONS/INTERPRETATION: No IMT changes were observed between the tofogliflozin and the conventional treatment groups. However, tofogliflozin is a safe and effective treatment option for managing primary CVD risk factors in this population.

Autonomic neuropathy has been reported in autoimmune rheumatic diseases (ARD) including Sjögren's syndrome, systemic sclerosis, rheumatoid arthritis, and systemic lupus erythematosus. However, the pathophysiological mechanism underlying autonomic dysfunction remains unknown to researchers. On the other hand, autoimmune autonomic ganglionopathy (AAG) is an acquired immune-mediated disorder, which causes dysautonomia that is mediated by autoantibodies against ganglionic acetylcholine receptors (gAChRs). The purpose of this review was to describe the characteristics of autonomic disturbance through previous case reports and the functional tests used in these studies and address the importance of anti-gAChR antibodies. We have established luciferase immunoprecipitation systems to detect antibodies against gAChR in the past and determined the prevalence of gAChR antibodies in various autoimmune diseases including AAG and rheumatic diseases. Autonomic dysfunction, which affects lower parasympathetic and higher sympathetic activity, is usually observed in ARD. The anti-gAChR antibodies may play a crucial role in autonomic dysfunction observed in ARD. Further studies are necessary to determine whether anti-gAChR antibody levels are correlated with the severity of autonomic dysfunction in ARD.

The physical properties of various white bread doughs made from the flours of 'Harunoakebono' and 10 genotypes of its near-isogenic lines with different compositions of high molecular weight glutenin subunit (HMWGs) were measured with the Creep method based on a Maxwell-2-element model. The expansion stress in the proofing process of various doughs was obtained by a numerical calculation method. The results indicated that doughs with high elastic characteristics, namely large relaxation time (τ0) and regularity coefficient of viscosity (ηN), have high dough stress throughout the proofing process and high stress at the proofing end (σend) and conversely, the low elastic dough with the small τ0 and ηN has the completely opposite tendency. This study also showed that there are significantly high correlations between the calculated σend and bread-making quality (BMQ) such as gas retention of dough and specific loaf volume (SLV). These results showed that BMQ, represented by SLV, of various white bread doughs were greatly influenced by the dough's physical properties, especially τ0 and ηN, which change with differences in the compositions of the HMWGs.
RESUMEN
Previously, we have detected the expression of 2 lipocalin genes (lp1 and lp2) in the olfactory epithelium of the Japanese newt Cynops pyrrhogaster. Recombinant proteins of these genes (Cp-Lip1 and Cp-Lip2, respectively) exhibited high affinities to various odorants, suggesting that they work like the odorant-binding proteins (OBPs). However, the physiological functions of OBP generally remain inconclusive. Here, we examined the effect of Cp-Lip1 on the electrophysiological responses of newt olfactory receptor cells. We observed that the electro-olfactogram induced by the vapor of an odorant with high affinity to Cp-Lip1 appeared to increase in amplitude when a tiny drop of Cp-Lip1 solution was dispersed over the olfactory epithelium. However, the analysis was difficult because of possible interference by intrinsic components in the nasal mucus. We subsequently adopted a mucus-free condition by using suction electrode recordings from isolated olfactory cells, in which impulses were generated by puffs of odorant solution. When various concentration (0-5 µM) of Cp-Lip1 was mixed with the stimulus solution of odorants highly affinitive to Cp-Lip1, the impulse frequency increased in a concentration-dependent manner. The increase by Cp-Lip1 was seen more evidently at lower concentration ranges of stimulus odorants. These results strongly suggest that Cp-Lip1 broadens the sensitivity of the olfactory cells toward the lower concentration of odorants, by which animals can detect very low concentration of odorants.
