Cytokines in the central nervous system of mice during chronic relapsing experimental allergic encephalomyelitis

Abstract

Clinical disease phases of chronic relapsing experimental allergic encephalomyelitis (CREAE) in the Biozzi AB/H mouse model are associated with extensive cellular infiltration of the central nervous system, principally the spinal cord. The activation of these cells is further suggested by the immunocytochemical demonstration of cytokines (migration inhibition factor, interferon-gamma, tumour necrosis factor-alpha, and interleukins 1, 2, and 3) within these infiltrates. The in vitro functions attributed to these cytokines indicate their potential role in cell recruitment, activation, and differentiation of the ongoing immune response which could contribute to the pathogenesis of disease.
