Phagocytic capacity of human leukocytes preincubated with Imuran and prednisone. 1983

D Kotulová, and J Stefanovic

The phagocytic and microbicidal activities of human polymorphonuclear leukocytes (PMNL) were tested after a short-term preincubation of phagocytic cells with Imuran or Prednisone, using C. albicans strains as a test organism. The tests showed that both immunosuppressive agents reduced significantly the microbicidal activity of PMNL cells by 35-40%. Detectable differences in the phagocytic activity and phagocytic index values were not statistically significant. The decreased ability of PMNLs to kill ingested C. albicans strains appears thus to sensitively reflect the altered PMNL function and can be utilized in the biologic monitoring of immunosuppression. The reduced microbicidal potential of phagocytic cells may be also one of the causes of recurrent microbial infections that are so frequent in immunosuppressant-treated patients.

UI	MeSH Term	Description	Entries
D007108	Immune Tolerance	The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.	Immunosuppression (Physiology),Immunosuppressions (Physiology),Tolerance, Immune
D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007166	Immunosuppressive Agents	Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
