RESUMEN

The development of personalized autologous dendritic cell anti-tumor vaccines (PDPW) against bladder cancer (BC) is a relevant issue that covers many aspects required for its standardization. The article presents personal experimental studies related to development of optimal conditions of transportation of biological material; temperature and temporary modes for the storage of the samples; the materials about the optimal method of disaggregation of the biomaterial; there has been shown a comparative analysis of different methods of tumor disaggregation; the selection of nutritious growth mediums and growth factors for urothelial carcinoma cells (UCC), the conditions of cryopreservation of tumor cells for maximum UCC viability, potentially suitable for creating PDPW against BC.

RESUMEN

Specific antitumor immunotherapy with autologous dendritic cell vaccines is one of the new approaches of modern medicine. For activation of dendritic cells highly immunogenic antigens are used, however optimal antigens in case of bladder cancer (BC) are still not researched. Cancer-testis antigens (CTA) are the most promising target in the context of creation of antitumor vaccines, because they are distinguished by pronounced immunogenicity, they are detected in different types of tumors and have limited pattern of expression in healthy tissues of grown-up organism. Regarding the level of mutational load, bladder cancer (BC) holds the third position among all malignant growths, which creates particular opportunities for use of immunotherapy in case of this disease. At chromosomal level most times the following cytogenetic anomalies specific for BC are detected: hyperploidies at 3, 7 and 17 chromosomes and deletion of 9p 21 locus. Besides, in the literature there is information about possible monosomy at 2, 3, 6, 8, 13, 14, 17 and frequent loss of Y chromosome in case of BC. Development of personified dendritic cell antitumor vaccines (PDAV) against bladder cancer (BC) is a relevant problem, which covers many aspects, necessary for its standardization. In particular, in case of cultivation of tumor cells under in vitro conditions their transformation goes at higher pace in comparison with in vivo tumor development. Moreover, the article presents the results of the study of molecular-genetic features of BC of tumor cultures in case of long-term cultivation, the level of expression of CTA (MAGE, NY-ESO-1, GAGE, BAGE) by urothelial carcinoma cells (UCC). There has been described the karyotypes of cells of urothelial low differentiated carcinoma of high malignant potential at various passages with prolonged cultivation, as well as the correlation between cytogenetic profile and expression of tumor-specific cancer-testis antigens has been identified. There have been developed two verified cell line cultures of muscle invasive and muscle-non-invasive urothelial carcinoma, that are potentially useful for the producing of tumor-associated vaccines against BC.

RESUMEN

Evidence that enables us to identify, assess, and access the small airways in asthma and chronic obstructive pulmonary disease (COPD) has led INTERASMA (Global Asthma Association) and WAO to take a position on the role of the small airways in these diseases. Starting from an extensive literature review, both organizations developed, discussed, and approved the manifesto, which was subsequently approved and endorsed by the chairs of ARIA and GA2LEN. The manifesto describes the evidence gathered to date and defines and proposes issues on small airway involvement and management in asthma and COPD with the aim of challenging assumptions, fostering commitment, and bringing about change. The small airways (defined as those with an internal diameter <2 mm) are involved in the pathogenesis of asthma and COPD and are the major determinant of airflow obstruction in these diseases. Various tests are available for the assessment of the small airways, and their results must be integrated to confirm a diagnosis of small airway dysfunction. In asthma and COPD, the small airways play a key role in attempts to achieve disease control and better outcomes. Small-particle inhaled formulations (defined as those that, owing to their size [usually <2 µm], ensure more extensive deposition in the lung periphery than large molecules) have proved beneficial in patients with asthma and COPD, especially those in whom small airway involvement is predominant. Functional and biological tools capable of accurately assessing the lung periphery and more intensive use of currently available tools are necessary. In patients with suspected COPD or asthma, small airway involvement must be assessed using currently available tools. In patients with subotpimal disease control and/or functional or biological signs of disease activity, the role of small airway involvement should be assessed and treatment tailored. Therefore, the choice between large- and small-particle inhaled formulations must reflect the physician's considerations of disease features, phenotype, and response to previous therapy. This article is being co-published in Asthma Research and Practice and the World Allergy Organization Journal.

RESUMEN

Difficult to control atopic dermatitis (AD) presents a therapeutic challenge and often requires combinations of topical and systemic treatment. Causes of severe AD are individual in each patient (e.g. genetic, barrier function, allergies). In this review, we will examine the highly complex interplay among skin barrier abnormality, allergy, immune dysregulation and antimicrobial peptide as a trinity in the development of AD. Studying of pathogenesis of formation of the complicated current the AD is a key problem of successful control as contamination of skin, and allergic inflammation.
