The effects of 10 weeks of treatment with cadmium (Cd) on the immune function and resistance to coxsackievirus B3 (CB3)-induced myocarditis in female Balb/c mice were investigated. A 2mM dose of Cd in the drinking water did not influence mortality due to the CB3 infection. The inflammatory and necrotic lesions in the ventricular myocardium seven days after inoculation (2.94% of tissue section area) were not increased by Cd (2.82% of tissue section area). The response pattern of lymphocyte subsets in situ in myocardial inflammatory lesions was elucidated by an immune histochemical staining technique. With Cd treatment the number of cytotoxic T cells and B cells in these lesions decreased by 22% (n.s.) and 21% (p < 0.05), respectively. Spleen weight and the lymphoproliferative response to the B-lymphocyte mitogen increased by 19% (p < 0.05) and 23% (n.s.), respectively. The titers of neutralizing antibodies increased by 22% (n.s.) with Cd treatment. However, the activity of spleen T lymphocytes and spontaneous cell-mediated cytotoxicity (NK-cell) was unchanged. Thymus weight and WBC count in peripheral blood tended to decrease. Thus, Cd exposure seems to result in a decreased maturation and mobilization of T and B lymphocytes, but increased humoral immune host responses.

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.

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.

D009205	Myocarditis	Inflammatory processes of the muscular walls of the heart (MYOCARDIUM) which result in injury to the cardiac muscle cells (MYOCYTES, CARDIAC). Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies.	Carditis,Myocarditides
D009929	Organ Size	The measurement of an organ in volume, mass, or heaviness.	Organ Volume,Organ Weight,Size, Organ,Weight, Organ
D001835	Body Weight	The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.	Body Weights,Weight, Body,Weights, Body
D002104	Cadmium	An element with atomic symbol Cd, atomic number 48, and atomic weight 112.41. It is a metal and ingestion will lead to CADMIUM POISONING.
D003384	Coxsackievirus Infections	A heterogeneous group of infections produced by coxsackieviruses, including HERPANGINA, aseptic meningitis (MENINGITIS, ASEPTIC), a common-cold-like syndrome, a non-paralytic poliomyelitis-like syndrome, epidemic pleurodynia (PLEURODYNIA, EPIDEMIC) and a serious MYOCARDITIS.

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.
