It was demonstrated that all vitiligo patients, independently of the disease stage, have a significant decrease in the total number of T cells and an elevated level of peripheral blood lymphocytes and activated natural killers (CD56). The low level of T lymphocytes is associated with the increase in the number of CD3(+)4(+)8(+) cells, which are(More)
We have conducted a comparative study of the lymphocyte surface antigens in patients with atopic bronchial asthma (ABA) in an acute stage and during clinical remission of the disease using a wide variety of monoclonal antibodies. In patients with ABA, independently of the stage of the disease, we have observed a decline in the total number of T lymphocytes(More)
Conformational dynamics of a biologically active fragment of α-fetoprotein, the heptapeptide LDSYQCT, and its analogs obtained by site-directed substitutions of amino acid residues were studied. The conformational dynamics of the peptide were conservative under the substitutions Y17F, Y17S, and D15E. Substitutions C19A and S16V resulted only in local(More)
In this work, using molecular dynamics simulation, we study conformational and dynamic properties of biologically active penta- and tetrapeptides derived from fetoplacental proteins such as alpha-fetoprotein, pregnancy specific β1-glycoprotein, and carcinoembryonic antigen. Existence of correlation between flexibility of peptide backbone and biological(More)

The review describes the influence of serotonin (5-HT) and its receptor, transporter SERT and nuclear factor Nf-kB on the immune function of the body, particularly in the digestive tract. The mechanisms of the synthesis, metabolism and catab. olism of 5-HT are characterized. The targets for serotonin on cell level are immunoactive cells--neutrophils,(More)
