Immunodepression in Taenia crassiceps infection: restoration of the in vitro response to sheep erythrocytes by activated peritoneal cells. 1978

K L Miller, and A H Good, and R I Mishell

The in vitro response to sheep erythrocytes of mesenteric lymph node cells from mice infected with the larval cestode Taenia crassiceps is significantly depressed and can be restored to control levels by addition of activated peritoneal cells depleted of functional T or B lymphocytes. Adherent mesenteric lymph node cells from infected mice are unable to reconstitute the in vitro response to sheep erythrocytes of normal nonadherent cells. The responses of mesenteric lymph node cells from infected mice to the T-lymphocyte mitogens concanavalin A and phytohemagglutinin and the B-lymphocyte mitogen lipopolysaccharide are normal. Mesenteric lymph node cells from infected mice do not suppress the in vitro response to sheep erythrocytes of normal mesenteric lymph node cells. These results suggest that the immunodepression in T. crassiceps-infected mice is primarily the result of alterations in functional accessory cells.

D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008934 Mitogens Substances that stimulate mitosis and lymphocyte transformation. They include not only substances associated with LECTINS, but also substances from streptococci (associated with streptolysin S) and from strains of alpha-toxin-producing staphylococci.
