[Dynamics of the endo-DNAase activity of cell nuclei of mouse thymus and spleen lymphocytes during the immune response].
Endo-DNAse (mostly Ca/Mg-dependent endonuclease) activity was studied in extracts of lymphocyte cellular nuclei from the spleen and thymus of mice upon their immunization with sheep red blood cells. Endo-DNAses were detected by their action on super-stranded DNA pBR 322. It has been established that endo-DNAse activity considerably changes in the course of immune response. The changes start in the early (induction) phase of immune response, are characterized by certain regularities and are distinct in thymus and spleen lymphocytes. It is assumed that endo-DNAses of lymphocyte cellular nuclei are involved in antigen-dependent lymphocyte differentiation.
