Biomarkers for chimeric antigen receptor T cell therapy in B cell malignancies can assess therapeutic efficacy and toxicity / 中华检验医学杂志

Chimeric antigen receptor (CAR)-T cell immunotherapy have developed for nearly two decades and achieved great clinical success in the treatment of hematological malignancies. Efficacy monitoring and toxicity management of CAR-T cell immunotherapy are essential steps to ensure safety and improve overall survival in multicenter clinical trials and commercialized treatments. CAR-T cell immunotherapy related biomarkers can be used as an indicator of patient baseline characteristics, tumor biology, and CAR-T cell function. Besides, side effects during treatment can also be assessed by the biomarkers.

Effective and persistent antitumor activity of HER2-directed CAR-T cells against gastric cancer cells in vitro and xenotransplanted tumors in vivo

Human epidermal growth factor receptor 2 (HER2) proteins are overexpressed in a high proportion of gastric cancer (GC) cases and affect the maintenance of cancer stem cell (CSC) subpopulations, which are used as targets for the clinical treatment of patients with HER2-positive GC. Despite improvements in survival, numerous HER2-positive patients fail treatment with trastuzumab, highlighting the need for more effective therapies. In this study, we generated a novel type of genetically modified human T cells, expressing a chimeric antigen receptor (CAR), and targeting the GC cell antigen HER2, which harbors the CD137 and CD3ζ moieties. Our findings show that the expanded CAR-T cells, expressing an increased central memory phenotype, were activated by the specific recognition of HER2 antigens in an MHC-independent manner, and effectively killed patient-derived HER2-positive GC cells. In HER2-positive xenograft tumors, CAR-T cells exhibited considerably enhanced tumor inhibition ability, long-term survival, and homing to targets, compared with those of non-transduced T cells. The sphere-forming ability and in vivo tumorigenicity of patient-derived gastric cancer stem-like cells, expressing HER2 and the CD44 protein, were also inhibited. Our results support the future development and clinical application of this adoptive immunotherapy in patients with HER2-positive advanced GC.

Hypoxic pretreatment of human umbilical cord mesenchymal stem cells regulating macrophage polarization / 解放军医学杂志

Objective To investigate the effect of human umbilical cord mesenchymal stem cells (hUC-MSCs) on macrophage polarization under hypoxia. Methods hUC-MSCs were obtained by explants adherent culture and cultured under normoxia (21% O2) and hypoxia (5% O2). The multi-directional differentiation of hUC-MSCs was observed by osteogenic and adipogenic differentiation induction. Live/death staining was performed to detect the cell viability, and ELISA was executed to detect the protein content in supernatant of hUC-MSCs. Transwell chamber was employed to co-culture the hUC-MSCs cultured under normoxia and hypoxia and macrophage (THP-1) stimulated by lipopolysaccharide (IPS), then the polarization of THP-1 was detected by immunofluorescence, and the secretions of inflammatory factor and anti-inflammatory factor of THP-1 were detected by ELISA. Results hUC-MSCs cultured under hypoxia showed the ability of osteogenic and adipogenic multi-directional differentiation. Live/death staining showed the high cell viability of hUC-MSCs cultured under normoxia and hypoxia. The expression levels of prostaglandin E2 (PGE2) and indoleamine 2,3-dioxygenase (IDO) were significantly higher in the hUC-MSCs cultured under hypoxia than in those cultured under normoxia. hUCMSCs cultured under hypoxia promoted the polarization of THP-1 to M2, obviously reduced the expression of TNF-α and IL-1β, and increased the expression of IL-10 significantly. Conclusion hUC-MSCs cultured under hypoxia may promote the polarization of THP-1 to M2 and improve the viability of anti-inflammatory.

[Temporal and spacial expression of perlecan in dental pulp after injury].

PURPOSE: To investigate the temporal and special expressions and functions of perlecan in dental pulp of rats after injury. METHODS: Specimens of one side of maxillary molars of 24 male SD rats were collected 1,3,5,7 days after injury, and the other side were used as controls. The specimens were decalcified and embedded in paraffin, sliced by longitudinal section and stained by immunohistochemistry. The staining of perlecan and ß1 integrin were examined, and the average optical density (AOD) was compared. The measurement data were analyzed by ANOVA using SPSS 19.0 software package. RESULTS: The staining intensity of perlecan in dental pulp in the experimental group was significantly higher compared with that of the control group. The immunolocalization of perlecan in dental pulp was gradually progressed as the inflamed tissue was progressing after injury, and its AOD was significantly higher than that of control group (F=11.104,P>0.05), especially in the group of 1 d. The staining of ß1 integrin was generally enhanced in the pulp 3 d after injury, and its AOD was significantly higher than that of control group (F=124.18,P>0.05). CONCLUSIONS: Perlecan may play an important role in tissue defense mechanism after injury through regulating angiogenesis and inflammatory cell infiltration.

Clinicopathologic features and molecular analysis of enterovirus 71 infection: report of an autopsy case from the epidemic of hand, foot and mouth disease in China.

A 15-month boy with fatal hand, foot, and mouth disease (HFMD) exhibited atypical symptoms and progressed rapidly to death. An autopsy was performed the next day and tissue sections were stained for histopathological examination. His intestinal samples were tested for enterovirus 71 (EV71), and the whole-genome sequence of EV71 was analyzed. An autopsy revealed that the central nervous system, lungs, and gut displayed severe meningitis and brainstem encephalitis, remarkable pulmonary congestion, edema, moderate inflammatory infiltration, and hemorrhage as well as intestinal mucosal congestion, epithelial necrosis, thinning intestinal wall, and submucosal lymphoid follicular hyperplasia. The heart showed myocardial interstitial congestion, myocardial edema, and some inflammatory infiltrates. There were no significant alterations in the architecture of other organs. EV71 antigen and apoptotic cells were detected in brain, lung and intestine by immunohistochemical staining and TUNEL (TdT-mediated dUTP nick-end labeling) respectively. Intestinal contents and intestinal autopsy samples of this case were positive for EV71, and the EV71 strain was classified as subgenogroup C4. In China, the severe forms of HFMD were mostly caused by EV71 subgenogroup C4 infection. Severe intestinal damages may relate to EV71 subgenogroup C4 infection. Thus, children with severe EV71 HFMD may have serious pathological changes in their central nervous system, lungs, and gut. Physicians should pay special attention to infants with atypical symptoms, particularly in EV71 epidemic areas for early diagnosis and treatment.

[Association of liver histopathology and clinical features among patients with chronic hepatitis B virus infection].

OBJECTIVE: To explore the histopathological features of chronic hepatitis B virus (HBV) carriers and chronic hepatitis B (CHB) patients with mildly elevated serum alanine aminotransferase (ALT). METHODS: 105 patients were divided into three groups according to serum ALT levels: Group A [ALT level < or = 0.5 x upper limits of normal (ULN)], Group B (0.5 x ULN < ALT level < or = 1 x ULN) and Group C(1 x ULN < ALT level < 2 x ULN). Grade of liver inflammation and stage of liver fibrosis in the three groups were compared. The changes in clinical parameters were then observed in patients who had liver histopathological changes. RESULTS: Among 40.95% of the patients, hepatitis degree went to G2 or even worse; and among 30.43% of the patients whose ALT level were normal, the hepatitis degree reached G2 or even worse. In 26.67% of the patients, degree of fibrosis went to S2 or even worse, and for the 17.39% patients whose ALT level were normal, degree of fibrosis went to S2 or even worse. The aggravation of liver inflammation and fibrosis was correlated with ALT and hyaluronic acid increasing (all P < 0.05). CONCLUSIONS: Frequent monitoring of serum ALT and hyaluronic acid may help to understand histopathological changes in the liver. Liver biopsy applied to CHB should be regarded as a main basis if antiviral therapy should be conducted.

[Influence of MgO and TiO2 on mechanical properties of zirconia toughened alumina ceramics formed by gel-casting technique].

OBJECTIVE: The objective of this study is to investigate the influence of mechanical properties and sintering performance by adding 5% weight percentage aids to nano-compound zirconia toughened alumina (ZTA) ceramics. METHODS: Micrometer Al2O3 and nanometer ZrO2 (quality ratio 4:1) were used to get 55% volume percentage slurry. Magnesium oxide and titanium oxide were taken as aids which were 5% weight percentage of the Al2O3 and ZrO2 powder. Five groups (number 0, 1, 2, 3, 4 group) were divided according to different proportion of aids. After gel-casting, the porcelain pieces were sintered at 1150, 1200, 1300, 1400, 1450, 1500, 1600 degrees C for 2 hours. Static three-point flexure strength, line shrinkage, relative density were measured and scanning electron microscopy (SEM) was used to observe section. RESULTS: Number 1 (MgO 1%, TiO2 4%) group had the highest bending strength. It was (401.78+/-19.50) MPa after sintering at 1600 degrees C for 2 hours and was higher than 0 group (380.64+/-44.50) MPa. Bending strength became lower than 0 group when MgO was more than 2% or more than that weight percentage of ZTA powder. When MgO content was higher than 2% or more than that weight percentage, there was no difference in relative density raising rate between each sintering assistants groups. When the sintering temperature was higher than 1200 degrees C, all groups showed obvious line-shrinkage and the groups which contained sintering assistants were all was higher than 0 group. CONCLUSION: Adding MgO and TiO2 aids from 1% to 4% weight percentage of ZTA will promote fritting and increase ZTA nano-compound ceramics mechanical properties. Adding 2% MgO aids or more than that weight percent will has no obvious help to increase the relative density raising rate of ZTA nano-compound ceramics and will degrade the mechanical properties of ZTA nano-compound ceramics.

[Effects of fluid shear stress on apoptosis of osteoblasts and expression of bcl-2,Bax and caspase-3].

PURPOSE: The aim of the present investigation is to evaluate the effects of fluid shear stress on the cells of osteoblasts and to determine the mechanisms involved. METHODS: The fluid shear stress with a magnitude of 0 (control group), 0.6, 1.0, 2.0, 3.0, 4.0, 5.0 Pa was exerted on the third passage of osteoblasts for 1 hour,and incubation in static condition for 24 hours. The cell apoptotic index was tested by the terminal transferase dUTP nick end-labeling(TUNEL) method. The expression of bcl-2 ,Bax and caspase-3 were detected by immunohistochemical method. Statistical analysis was performed using SPSS11.5 software package for one-way ANOVA. RESULTS: The apoptosis of osteoblasts and the expression of bcl-2, Caspase-3 were not affected significantly by the fluid shear stress with a magnitude from 0 to 2.0 Pa(P>0.05) . But in the 3.0,4.0 and 5.0 Pa groups, the number of apoptotic cells and the expression of caspase-3 increased while the expression of bcl-2 decreased(P<0.05).There was no significant difference in expression of Bax in all groups. CONCLUSIONS: The physiological fluid shear stress does not affect apoptosis of osteoblasts. However,the fluid shear stress of over-magnitude may lead to the decrease the expression of bcl-2,which results in activation of caspase-3 and apoptosis of osteoblasts.
