We used this prototype "Cell Chip" to test, by means of flow cytometry, the immunomodulatory potential of 13 substances and were able to detect changes in cytokine expression in 12 cases (successful for cyclosporine, rapamycin, pentamidine, thalidomide, bis (tri-n-butyltin) oxide, house dust mite allergen (Der p I), 1-chloro-2,4-dinitrobenzene, benzocaine, tolylene 2,4-diisocyanate, potassium tetrachloroplatinate, sodium dodecyl sulphate and mercuric chloride; unsuccessful for penicillin G).

These findings further strengthen the concept that B10.S mice react to HgCl2 by preferential activation of their Th2 cells producing IL-4, whereas B10.D2 mice react to HgCl2 by preferential activation of their Th1 cells, which produce IFN-gamma and thus suppress antibody responses.

The monoclonal antibody OX22 defines a functional split within CD4+ T cells in the rat, with OX22high cells mainly producing interleukin 2 (IL-2) and interferon gamma and responsible for delayed-type hypersensitivity responses, and OX22low cells mainly producing IL-4 and -5 and responsible for providing B cell help.

Mercuric chloride (HgCl2) injections protect (Lewis x Brown-Norway) F1 (F1) rats against experimental autoimmune uveoretinitis (EAU) induced by immunization with the retinal S antigen (S-Ag); in contrast HgCl2-injected F1 rats develop EAU following transfer of lymph node (LN) cells from rats immunized with S-Ag alone.
In contrast, LN cells from diseased rats easily transferred EAU into naive F1 rats, produced significant IL-2 and IFN-gamma levels but barely exhibited mRNA for IL-4.

Mice of the susceptible A.SW strain showed a modest increase of TNF-alpha-, IFN-gamma-, and IL-4-producing cells after 4-6 days, and a very distinct increase of IL-4-producing cells on days 8-10.

The high total IgE levels and evidence showing ex vivo down-regulation of IFN gamma and in vivo up-regulation of IL-4 suggest that HgCl2-induced autoimmunity occurs in a Th2 lymphokine environment.
