PG - 67-71 AB - The inflammation of the reproductive system can affect reproduction causing partial or complete infertility. It is well known that lipopolysaccharide (LPS) triggers an inflammatory response in the whole organism, including immunologically privileged organs, e.g. the testicles. Adult male TCRalpha-/-, TCRdelta-/-, CD1d-/- and beta2m-/- on B10.PL (H-2(u)) and B10.PL control mice were intraperitonealy (i.p.) injected with lipopolysaccharide (LPS). The animals were killed 24h and 10 days post LPS treatment and their gonads were prepared for microscopic examination. Histological changes in the testes after LPS injection were found only in control B10PL and CD1d-/- mice. The experiments revealed disturbances in Leydig's glands structure, blood vessel dilatation in the interstitial tissue as well as degeneration of seminal tubule epithelium, disruption ofspermatogenesis and subsequent decrease of sperm cell number in the tubule lumen. These changes were noticed mainly 10 days after LPS treatment. Lack of either TCRalphabeta+ CD8+ or TCRgammadelta+ lymphocytes diminishes the response of testicular macrophages to LPS whereas the absence of CD1d-dependent NKT cells does not affect macrophage reactivity.
