The immunological response of spleen cells was examined during murine cytomegalovirus (MCMV) infection of germfree (GF) mice. GF mice were more susceptible to MCMV infection than specific pathogen-free (SPF) mice. Recovery from the acute phase of MCMV infection was delayed in GF mice as compared to SPF mice. During MCMV infection, the immune response of GF mice, measured in terms of mitogen and of antibody response to sheep erythrocytes, was more markedly depressed and the recovery from the depression was more delayed than in SPF mice. In MCMV-infected mice, natural killer (NK) cell activity was increased by day 1 and 2 post-infection, with similar kinetics in GF and SPF mice, suggesting that NK cells may be exerting the most potent antiviral effect during the early stage of MCMV infection.

UI MeSH Term Description Entries
D007694 Killer Cells, Natural Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

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.

D003586 Cytomegalovirus Infections Infection with CYTOMEGALOVIRUS, characterized by enlarged cells bearing intranuclear inclusions.
