| abstractText | Lurcher mutant mice are characterized by a fast and almost total loss of olivocerebellar neurones during the first postnatal month, associated with a chronic inflammatory state. To test their brain sensitivity to proinflammatory cytokines, we assessed the behavioural responses of adult male Lurcher and wild type to an i.p. or i.c.v. injection of rat recombinant IL-1 beta, and lipopolysaccharide (LPS). IL-1 beta (15 micrograms kg-1, i.p. or 1 ng i.c.v.) decreased social exploration measured 2, 4 and 6 h later, and this decrease was significantly more pronounced in Lurcher than in wild type mice. LPS (60 micrograms kg-1, i.p. or 5 ng i.c.v.) decreased social exploration measured 2 and 4 h later, and this effect was also significantly more marked in Lurcher than in wild type mice. These results suggest that the chronic inflammatory state which characterizes Lurcher mice renders these animals more sensitive to the effects of cytokines such as IL-1 beta and LPS. This difference may be due to the higher reactivity of brain macrophages and glial cells to LPS and IL-1 in Lurcher mice than in wild type. |
