2457504 Caltabiano MM, Poste G, Greig RG: Isolation and immunological characterization of the mammalian 32-/34-kDa stress protein. Exp Cell Res. 1988 Sep;178(1):31-40.

Challenge of mammalian cells with heavy metals or sulfhydryl-reactive agents including sodium arsenite induces the de novo synthesis of a 32-/34-kDa stress protein (p32) (M.

Intra-gastric exposure to arsenic (as sodium arsenite) for 30 days (1, 0.1, or 0.01 mg/kg/day), reduced the proportion of CD4+ cells and the CD4+/CD8+ ratio in the spleen, increasing the proportion of CD11b+ cells.

Among various compounds tested thus far, methyl methanesulfonate, N-methyl-N'-nitro-N-nitrosoguanidine, L-ascorbic acid, sodium deoxycholate, p-tosyl-L-phenylalanine chloromethyl ketone, p-tosyl-L-lysine chloromethyl ketone, 3,3'-diaminobenzidine, and some of the metal salts stimulated the synthesis of p32 to varying extents. p32 might be one of the heat shock proteins because its synthesis was also stimulated by heat shock or sodium arsenite.

The library was constructed from mRNA extracted from the cells treated with sodium arsenite, which stimulates the p32 expression most effectively among various agents so far tested.

Enhanced expression of the 32- and 34-kDa polypeptides (p32 and p34) preceded or paralleled the synthesis of the other stress proteins.

Arsenic susceptibility of lymphocyte subpopulations (T helper (Th), CD4+; T cytotoxic (Tc), CD8+) and whether arsenic effects are gender related are still to be determined.

Arsenite also decreased early activation (surface CD69+ expression) in both CD4+ and CD8+, and decreased total CD8+ count without significantly affecting CD4+, supporting that the cellular immune response mediated by cytotoxic T cells is an arsenic target.

The accumulated data indicated that the cell surface expression of Ag was clearly enhanced by several stressors, such as TNF, L-azetidine-2-carboxylic acid, and sodium arsenite.
