Morphofunctional characteristics of the immune system in CBA and C57Bl/6g mice.

We studied peculiarities of morphofunctional organization of the immune system in C57Bl/6g and CBA mice differing by their susceptibility to various types of infectious agents. The revealed differences in the structure of lymphoid organs, T lymphocyte subpopulation ratio and their differentiation into Th1/Th2 cells after mitogen stimulation drove us to a conclusion on genetically determined regularities in the development of the immune response in these animal strains.
