title: The analgesic defect of C57BL/6J-bgJ/bgJ (beige-J: Chediak-Higashi syndrome) mice transmitted by adoptive transfer of spleen cells to normal littermates.
abstract: We recently discovered and reported that C57BL/6J-bgJ/bgJ (beige-J) mice have a deficiency in their analgesic response to intracerebroventricularly-administered morphine in the tail-flick test. Postulating a link between these findings and the known immunological defect of beige-J mice (Chediak-Higashi syndrome), we examined the effect of splenectomy on beige-J mice and the adoptive transfer of their mononuclear spleen cells to normal littermate controls (2 x 10(7) cells via tail vein). Eight days after these interventions, the splenectomized beige-J mice responded nearly as well as normal mice to centrally administered morphine in the tail-flick test. The adoptive transfer recipients, in contrast, nearly completely lost their response to the analgesic action of morphine in this test. From the combined results, the spleen appears to be a significant factor in the analgesic defect of beige-J mice and, furthermore, mononuclear splenocytes appear to be the source of a substance that can transfer this defect to otherwise normal animals.
