For their protection from host cell immune defense, intracellular pathogens of eukaryotic cells developed a variety of mechanisms, including secretion systems III and IV which can inject bacterial effectors directly into eukaryotic cells. These effectors may function inside the host cell and may be posttranslationally modified by host cell machinery.(More)
We studied the effects of immunization with a conjugate of carrier protein and hexasaccharide ligand related to a fragment of capsular of Str. pneumoniae serotype 14 polysaccharide chain on activation of innate and adaptive immunity. It was found that two-fold immunization with the glycoconjugate adsorbed on aluminum hydroxide significantly increased the(More)
We report the effect of a bovine serum albumin (BSA) conjugate of a synthetic hexasaccharide (HS) related to the fragment of the capsular polysaccharide (PS) of Streptococcus pneumoniae type 14 on the stimulation of innate immune system and the subsequent development of a PS-specific antibody response. Glycoconjugate (GC) in the presence (GC + AL) or(More)
The minimal vaccination dose of tumor cells was determined on experimental models. The effectiveness of antitumor immunotherapy with activated natural killer cells or dendritic cell vaccine (monotherapy or combined treatment) was evaluated in vivo. The inhibition of tumor growth was more pronounced after combination therapy with activated natural killer(More)
Tγδ and B1 lymphocytes are essential components of the mucosal immune system, activated directly by different bacterial and viral ligands without additional costimulatory signals and preprocessing of other immune effectors. This ability enables the immune system to provide rapid protection against pathogens and contributes to the decoding mechanism of the(More)
