Ectromelia virus-specific cytotoxic T (Tc) cell precursors were present in the draining popliteal lymph node of all strains of mice tested at 2 to 3 days after footpad inoculation of a high dose (10(5) p.f.u.) of the virulent Moscow strain of ectromelia virus. To detect this response it was necessary to culture lymph node cells from infected mice in the presence of T cell growth factors and to use the more sensitive neutral red assay for measuring cytotoxicity. Cells with lytic activity were virus-specific, major histocompatibility complex-restricted TC cells. C57BL/6J resistant mice, which express a single dominant gene conferring innate resistance had virus-specific TC cell precursors 1 to 2 days sooner than did susceptible BALB/b mice. This TC cell-mediated immune response early after infection could account for the barrier to virus dissemination known to operate 1 to 2 days after infection to slow virus passage into the lymphoreticular system.

UI	MeSH Term	Description	Entries
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.

D008285	Major Histocompatibility Complex	The genetic region which contains the loci of genes which determine the structure of the serologically defined (SD) and lymphocyte-defined (LD) TRANSPLANTATION ANTIGENS, genes which control the structure of the IMMUNE RESPONSE-ASSOCIATED ANTIGENS, HUMAN; the IMMUNE RESPONSE GENES which control the ability of an animal to respond immunologically to antigenic stimuli, and genes which determine the structure and/or level of the first four components of complement.

D003602	Cytotoxicity, Immunologic	The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013602	T-Lymphocytes, Cytotoxic	Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.
