Abstract
Mucin 1 (MUC1) is a multistructural and multifunctional protein that is involved in regulating diverse cellular activities. This strongly glycosylated transmembrane protein forms a mucous gel on the surface of epithelial cells that protects the cells from injury. MUC1 acts as a signaling molecule and transcription factor modulating metabolism and resistance to bacterial-induced inflammation. This article presents a review of the relationship between structural and functional changes of the MUC1 and the characteristics of cancer cells. The alteration in MUC1 expression level, a number of structural forms, protein glycosylation and localization occurs in cancer cells. These alterations lead to metabolic reprogramming associated with proliferation, resistance to hypoxia and angiogenesis which affects the survival of cancer cells. Furthermore, cancer cells can take advantage of MUC1 interaction with adhesion molecules for invasion and metastasis. Thus, MUC1 plays a key role both in the homeostasis of epithelial cells and in cancer progression. Understanding the role of MUC1 expression in tumor cells survival is important for the development of new monitoring and therapeutic approaches for the treatment MUC1 positive maligancies.

Abstract
The immune-enzyme analysis was applied using anti-CD38 monoclonal antibodies to detect serum content of total (sCD38) and oligomeric fractions of soluble molecules CD38 (ol.sCD38) in patients with cervix cancer and malignant neoplasms of uterine body. The three- and four-fold increasing of serum level of sCD38 is demonstrated both under cervix cancer and malignant neoplasms of uterine body. The level of ol.sCD38 decreased in patients with cervix cancer and increased in case of patients with malignant neoplasms of uterine body. The serum content of ol.sCD38 was increased under adenocarcinoma of uterus and glandular epidermoid cancer. The content of sCD38 increased under adenocarcinoma of uterus but decreased under sarcoma of uterus. The highest level of soluble molecules of CD38 was established in patients with highly differentiated tumors and under invasion into endometrium but not into miometrium. On the whole, alterations in content of soluble molecules CD38 are associated with characteristics of tumor process that indicates at their monitoring significance under malignant neoplasms of uterus.

Abstract
Fas-induced apoptosis plays an important role in the mechanisms of tissue injury in myocardial infarction. The level of membrane Fas mRNA was elevated during the postinfarction period in the blood of patients and did not change in response to levocarnitine. The mRNA level of soluble Fas, inhibiting Fas-dependent apoptosis, remained normal during the first 7 days, but increased 14 days after myocardial infarction, which corresponded to previously detected increase of serum level of soluble Fas molecules. Addition of levocarnitine, inhibiting Fas-dependent apoptosis, to therapy caused no changes in the level of soluble Fas mRNA, presumably because of similar effects of soluble Fas and levocarnitine on the apoptotic processes in myocardial infarction.

Abstract
AIM Characteristics of quantitative and qualitative composition of cultured microorganisms isolated from axilla skin of practically healthy individuals. MATERIALS AND METHODS 77 practically healthy individuals aged 18 to 40 years were examined. Species identification of microorganisms was carried out byculture-morphologic, tinctorial and biochemical properties using time-of-flight mass spectrometer and rpoB gene amplification with subsequent direct sequencing. RESULTS Quantitative evaluation of microbial composition of axilla skin microbiota in most of the practically healthy individuals varied in the 4-5 lg CFU/ml interval, whereas seeding of skin by this microbiota at the level of 8 lg CFU/ml was not detected. 158 strains of 24 microorganism species were identified in this biotope. Most of these strains (68.9%) belonged to Corynebacterium genus, 21.6% of strains--to Staphylococcus genus, 7.6% of strains--to Micrococcus genus and 1.9% of strains--Candida albicans. 16 species of corynebacteria were isolated with predomination of C. tuberculostearicum (40.3%), C. amycolatum (18.4%) and C. ureicelerivorans (14.8%) strains. The microbial landscape in most of the examined individuals (77.9%) was presented by microorganism association. CONCLUSION Quantitative and qualitative species composition of cultured microorganisms isolated from axilla skin biotope of practically healthy individuals was characterized for the first time.

Abstract
AIM Study of features of NK-cell response to the effect of recombinant IFN-alpha in complex with evaluation of the ability to synthesize inherent IFN-alpha in patients with frequently recurrent herpes simplex (FRHS). MATERIALS AND METHODS 48 patients with genital (n = 31), labial (n = 10) and mixed localization (n = 7) FRHS diagnosis were observed. 31 healthy donors composed the control group. MC were cultivated in the presence of a recombinant human IFN-alpha2b at the concentration of 10, 100 and 1000 U/ml for 24 hours. NK-cell response to the effect of IFN-alpha was evaluated after 24 hours using flow cytometry by degranulation reaction and in the NK-activity test. IFN-alpha synthesis was evaluated in HSV-1, HSV-2 and Newcastle disease virus stimulated cell supernatants by EIA method. RESULTS Patients with FRHS were established to be a heterogeneous group by parameters in the IFN-alpha/NK-cell cytotoxicity system. 2 types of NK-cell response to the stimulation by recombinant IFN-alpha were identified. Type A is characterized by a decrease of NK-cell response to IFN-alpha in the remission phase and does not have this defect in the exacerbation phase. Synthesis of inherent IFN-alpha in response to viral inductors for type A was comparable with the response in healthy donors in both phases. On the contrary type B having normal sensitivity of NK-cells to IFN-alpha in the remission phase is characterized by a decrease of this parameter in the exacerbation phase for more than 3 times. Synthesis of inherent IFN-alpha in response to viral inductors during type B is increased in the remission phase and decreased in the exacerbation phase. CONCLUSION During immune-correcting therapy of FRHS a personalized approach taking into account features of NK-cell response to IFN-alpha is necessary, because types A and B have principal differences by cytotoxicity parameters of NK-cells and their change under the effect of IFN-alpha, as well as by parameters of IFN-alpha synthesis in response to viral inductors at various phases of the clinical process.

Abstract
AIM Study the features of immune-reactivity expression in mucosa depending on their topicity and etiopathogenesis of the pathological process. MATERIALS AND METHODS Data from 30 clinically healthy children and 77 children with acute and recurrent diseases of respiratory tract: 51--with acute and 15--with chronic bronchitis; as well as 132 women: 41--with active stage of acute urogenital chlamydia infection, 29--with recurrent chronic process, 30--with non-recurrent form and 32 clinically healthy women were analyzed. Saline and urogenital tract mucosa discharge was analyzed for IgG, sIgA and secretory component, IL-1beta, 4, 6, 8, 9, 10, 12, IFNgamma, TNFalpha and GM-CSF, TLR-2, TLR-3, TLR-4, TLR-8 gene expression levels as well as content of lysozyme, total protein and leucocytes. RESULTS Solidity, universality and practically single-stage triggering of mucosa immune reaction mechanisms to intervention by foreign agents regardless of their localization was confirmed. A dependence of immune-reactivity expression on the form of pathologic process, its localization and qualitative and quantitative characteristics of the infectious agents was clearly seen. The highest level of clinical-laboratory and immunological parameters is inherent for patients with acute processes in urogenital tract (cervical canal and urethra), especially cause by mixed infections. CONCLUSION Immune diagnostic parameters of mucosa among which TLR system is especially notable have high information properties allowing not only diagnostics of inflammatory process but also differentiating its form and character our course.

Abstract
AIM Analyze genetic and phylogenetic interrelations between S. pneumoniae strains isolated from meningitis patients and carriers. MATERIALS AND METHODS 23 S. pneumoniae isolates (9 from bacterial meningitis patients, 9 from nasopharynx of bacterial carriers, 5 strains from museum collection of Gabrichevsky Moscow Research Institute of Epidemiology and Microbiology) were studied. S. pneumoniae ATCC 49619, S. mitis ATCC 49456 served as control strains. S. pneumoniae serotype determination was carried out in latex-agglutination reaction and quelling reaction. Multiplex PCR according to WHO protocols was used for molecular-genetic study and pneumolysin (ply), autolysin (lytA), surface cellular adhesin A (psaA) and capsule polysaccharide (cpsA) gene determination. Multilocus sequence-typing was carried out according to WHO scheme for 7 "housekeeping" segments--aroE, gdh, gki, recP, spi, xpt and ddl. Computer programs from available internet resources were used for data processing and dendrogram building. RESULTS; The S. pneumoniae isolates analyzed were established to belong to 19 sequence types that may be combined into 4 subclusters. Results of molecular-genetic and serologic typing were completely comparable. CONCLUSION Attribution of isolates from the same serotype and serogroup to different sequence-types gives evidence on the ongoing changes within serotype and as a result changes in allele profile of circulating S. pneumoniae isolates. Membership of isolates in separate subclusters gives evidence on close evolution relationship between isolates obtained from patients with bacterial meningitis and carriers. Certain isolates had not previously been registered in Russia and were probably imported from the territories of other countries.

Abstract
The fact that many infectious diseases are not effectively controlled with etiotropic drugs determines the relevance of a search for alternative methods, particularly those based on the modulation of immunity. The review analyzes rational approaches to the immunotherapy of infectious diseases, such as regulation of acquired immunity; correction of the quantitative and qualitative composition of the intestinal microbiota; and modulation of innate immunity. Among the drugs affecting the innate components of an immune response, the derivatives of muramyl dipeptide (MDP), a structural subunit of bacterial cell wall peptidoglycan, stand out in the context of a detailed study of the cellular and molecular mechanisms of action. The fact that it is expedient to clinically apply these immunomodulators in many diseases accompanied by inadequate infection control is beyond question. It is demonstrated that muramyl peptides (MP) may be also used to prevent excessive inflammatory responses. The adjuvant properties of MDP and its analogues can be employed for therapeutic vaccination. The data that the signals transmitted through NOD-like receptors (MP sensors) regulate intestinal homeostasis suggest that there is some potential for the use of MDP derivatives for the correction of dysbiosis and related immune disorders. Whatever the purpose of immunomodulation, the key to its effectiveness is to personalize the choice and regimens of immunotropic drugs.

Abstract
According to the etiology of acute pancreatitis, the authors identified the most common phenotypes of superficial antigens of peritoneal macrophages: CD14(+) CD25(-)CD64(-)HLA-DR(-) in acute biliary pancreatitis, CD14(+) CD25(+)CD64(+)HLA-DR(+) in nonbiliary pancreatitis; moreover, all the patients were found to have increased expression of early (CD25+) and late (HLA-DR+) markers of cell activation. A comparative study was conducted and the most informative tools to evaluate the adhesive, cytokine-producing, phagocytic, and oxygen-dependent activities of peritoneal macrophages were recognized.

Abstract
Based on the results of the comparative analysis concerning relatedness and evolutional difference of the 16S - 23S nucleotide sequences of the middle ribosomal cluster and 23S rRNA I domain, and based on identification of phylogenetic position for Chlamydophila pneumoniae and Chlamydia trichomatis strains released from monkeys, relatedness of the above stated isolates with similar strains released from humans and with strains having nucleotide sequences presented in the GenBank electronic database has been detected for the first time ever. Position of these isolates in the Chlamydiaceae family phylogenetic tree has been identified. The evolutional position of the investigated original Chlamydia and Chlamydophila strains close to analogous strains from the GenBank electronic database has been demonstrated. Differences in the 16S - 23S nucleotide sequence of the middle ribosomal cluster and 23S rRNA I domain of plasmid and non-plasmid Chlamydia trachomatis strains released from humans and monkeys relative to different genotype groups (group B- B, Ba, D, Da, E, L1, L2, L2a; intermediate group - F, G, Ga) have been revealed for the first time ever. Abnormality in incA chromosomal gene expression resulting in Chlamydia life and development cycle disorder and decrease of Chlamydia virulence can be related to probable changes in the nucleotide sequence of the gene under consideration.

Abstract
Beta-cyclohexylmethyl-, beta-cyclohexylethyl-, and beta-4-tert-butyl-cyclohexyl glycosides of muramyl dipeptide were shown to increase the resistance of mice to intraperitoneal infection with cultures of Staphylococcus aureus and Escherichia coli. These compounds increased the production of cytokines by mononuclear cells from healthy donors. Beta-cyclohexylethyl glycoside of muramyl dipeptide was more potent than muramyl dipeptide and other derivatives in increasing in vivo antibacterial resistance and in vitro production of interleukin-1beta, interleukin-6, tumor necrosis factor-alpha, and interferon-gamma;. This glycopeptide had a strong stimulatory effect on the production of interleukin-4 and tended to stimulate the synthesis of interferon-alpha. Beta-cyclohexylmethyl glycoside of muramyl dipeptide was most potent in stimulating the production of interleukin-4. Biological activity of beta-4-tert-butyl-cyclohexyl glycoside of muramyl dipeptide was lower than that of other glycosides of muramyl dipeptide.

Abstract
The study group was comprised of 27 practically healthy children, 51 patients with acute bronchitis, 15 with chronic bronchitis and 11 with pneumonia. It was shown that changes of microbiocoenosis in back of the throat (BOT) were related to increased mucosal contamination with normal microflora and opportunistic microorganisms. The highest degree of contamination was observed in children with acute bronchitis. Normocoenosis was detected only in 13 practically healthy children. The disorders of microbiocoenosis took the form of disbiosis and acute inflammatory processes in patients with acute and chronic bronchitis and pneumonia. However, the large amount of normal flora together with the high Ig level ensured marked colonization resistance as evidenced by the values of natural colonization coefficient of nasopharyngeal epithelium (NCCNE) and balance coefficient (BC). These data suggested development of compensated secondary immunodeficiencies. In patients with acute bronchitis and pneumonia, local synthesis of Ig prevailed. It is shown that BC can be used to screen children for disorders of mucosal immunity. The presence of increased saliva IgE levels in patients with acute and chronic bronchitis supports the generally accepted concept of bronchi as a "shock organ" in allergic condition. It was demonstrated that IgE levels in saliva increase earlier than in serum and may be used as a prognostic criterion in patients with bronchopulmonary pathology.

Abstract
Cellular immunity plays a central role in immune response to chlamydial infection, and soluble forms of immune cell membrane antigens take part in the regulation of immune response. Using an immunoenzymatic method, we determined serum levels of soluble HLA molecules (sHLA-I and sHLA-DR) and soluble CD25 molecules (sCD25) in patients with genital chlamydial infection. Specimens from patients with nonspecific inflammation of the urogenital tract were studied and healthy volunteers served as controls. We revealed that serum levels of sHLA-DR and sCD25 increased 3.5- and 2.3-fold, respectively, during chlamydial infection, while the levels of sHLA-I were not changed. Nonspecific inflammation of the urogenital tract was characterized by a 1.5-fold increase in sHLA-I, a 1.6-fold decrease in sCD25, and no changes of sHLA-DR levels in comparison with healthy volunteers. We concluded that Th1 immune responses might dominate during genital chlamydial infection contrary to the state of nonspecific inflammation of urogenital tract.

Abstract
The inhibitory effect of adenosine on aggregation of human platelets activated by platelet activating factor (PAF), ADP and serotonin (5-HT) were examined using native platelets from blood of volunteers. Platelet aggregation was determined by Born's method. Effective adenosine concentrations (IC50) which had inhibited platelet aggregation were found to be 0.63 +/- 0.11, 1.47 +/- 0.31 and 0.64 +/- 0.18 microM, respectively. It was shown that 10 microM adenosine inhibited PAF-induced platelet aggregation completely. The same adenosine concentration blocked ADP- and 5-HT-induced aggregation only partially. Adenosine is physiological inhibitor of human platelet aggregation in administration of PAF, ADP and 5-HT. Specific characteristics of adenosine modulating effect on these ligands was elicited.

Abstract
Cellular immunity and activity of enzymes of xenobiotic metabolism have been investigated. It has been shown that administration of benzene induces a stable immune deficiency syndrome characterized by a decrease in the quantity if antibody-forming cells, T-killers and T-suppressors. The activity of enzymes (cytochrome P-450 and cytochrome C reductase) was also inhibited. It has been shown that anabol can stimulate the parameters of cellular immunity and enzyme activity. Benzene intoxication was demonstrated to be a model of immune deficiency syndrome similar to the clinical pattern. Anabol was shown to be an effective immunomodulator.

Abstract
Effect of T-activin on some xenobiotic metabolizing enzymes and several immunity parametres in secondary immune deficiency (subacute and chronic benzene intoxication) were investigated. T-activin was shown to regulate the xenobiotic metabolizing enzyme system. The compound decreased the enzymatic activity in subacute benzene intoxication, approaching their values up to the control level. In chronic benzene intoxications, which were accompanied by decrease in xenobiotic metabolizing enzymes activity, except of glutathione-S-transferase, T-activin stimulated these enzymes. At the same time, T-activin increased some immunological parameters in these models. Thymus-tropic peptides appear to be the bioregulators of some in vivo systems.

Age-related differences with respect to the number of T-lymphocytes and activity of lymphocyte glutathione S-transferase were observed in the normal animals, the other indices such as activity of natural killer cells, K-cells, blast cell transformation with concanavalin A and activity of cytochrome c-reductase being independent of the age. Administration of anabol to healthy animals did not alter their immunoenzymatic status. Chronic alcohol intoxication was accompanied by development of secondary immune deficiency characterized by lower immunological indices and lower activity of xenobiotic metabolism enzymes in lymphocytes. Daily exposure to 0.8 g of anabol for 12 days at this background resulted in normalization of the above indices.

Abstract
The influence of immunoregulating humoral thymus factor T-activin (fraction AFT-6) on the activity of xenobiotic metabolism enzymes (EMX) and cellular-dependent cytotoxicity was investigated in germ-free guinea-pigs. Germ-free and conventional animals were injected 5 micrograms of T-activin intraperitoneally, on 3 successive days. The control animals were injected a physiologic saline. A day after the last injection the animals were killed, and EMX and K cell activity was measured. It was found that EMX activity in germ-free animals was decreased. T-activin stimulated cytochrome P-450, NADP-cytochrome-C-reductase, glutathione-S-transferase, benzopyrene hydroxylase and epoxyhydrase activity. In conventional animals the activity of these enzymes remained unchanged under the influence of T-activin. K-cell activity in germ-free animals was decreased, as compared to conventional guinea-pigs. Under the influence of T-activin the parameter increased and stood at about 70% of normal values.

Abstract
Specific suppressor T cells (SSTC), primed in vivo with H-2 antigens, have been shown previously to inhibit DNA synthesis in the one-way, three-cell mixed lymphocyte reaction (MLR) provided that (a) the stimulator cells bear the priming H-2 antigens, and (b) the responder cells possess IC + S regions homologous to those of the SSTC. Anti-B10.A B10.A(2R) SSTC (anti-Dd) and anti-A.AL A.TL SSTC (anti-Kk) are shown here to be able to inhibit the DNA synthesis triggered in MLR, not only by the corresponding antigens, Dd and Kk, respectively, but also by irrelevant, third-party H-2 and Mls products provided that the corresponding and third-party antigens are presented on the same stimulator cell. If stimulator H-2 regions, whose products interact with SSTC and responders, are located on different stimulator cells within the particular MLR, SSTC activity is not elicited. Participation of cytotoxic T lymphocytes in DNA-synthesis suppression is ruled out. Direct contact or location of the inhibited responder cell very close to SSTC is considered to be required for the development of SSTC activity.

Abstract
Rats were immunized with mouse lymphocytes enriched by the absorption-elution technique with specific suppressor T-cells (STC) immune to antigens of the H-2 complex. The anti-suppressor sera (ASS) obtained being absorbed with mouse erythrocytes and lymph node cells killed in the presence of complement about 30 per cent of the STC-enriched cell population and inactivated the STC in vitro function in a selective fashion, not affecting the function of other T-cell subclasses, killers and MIF-producers, immune to the same H-2 antigens. The STC inactivating ASS action occurred partly in the absence of complement irrespective of the STC strain origin, STC immunological specificity in the H-2 system and the intensity of the STC activity. This ASS action was abolished by exhaustion of antibodies only with STC containing cell suspensions. In contrast, intact (non-enriched) mouse STC appeared to be able to induce a mixture of rat antibodies inactivating partly all three T-cell subclasses assayed. Infections of ASS to mice prevented them from the in vivo STC generation and gave rise to inhibition of the syngeneic tumor growth in the specifically preimmunized mice.
