Numerous reviews have documented immune modulation in response to metal, pesticide and organic contaminants in fish4,19,37,135. Assays traditionally used to assess perturbations of immune function in fish fall into three broad categories pathogen challenge models, assays that monitor immune suppression/activation or immuno-pathology. Immune suppression/activation is usually measured with assays of phagocytosis, respiratory burst, cell proliferation, as well as quantification of soluble factors such as lysozyme, serum antibody, CRP or complement. 

Stahl et al. 1969) however, this effect may have been due to altered peripheral hemodynamics. Acute inhalation exposure had no effect on survival from a bacterial pathogen challenge in mice (Aranyi et al. 1986). Histological evaluation of lymphoreticular tissues from rats and mice (including lymph nodes, thymus, and speen) have not revealed any lesions attributable to 1,1,1-trichloroethane exposure (Adams et al. 1950 Calhoun et al. 1981 Cornish and Adefuin 1966 Kjellstrand et al.

The response is a sequential cascade of transcriptional regulatory events. Individual genes (notably the proinflammatory cytokines) are induced transiently and then repressed (Wells et al 2003a). The transient nature of the transcriptional regulatory response to LPS (and any other pathogen challenge) is absolutely crucial to resolution.
