Abstract

Inflammatory cells, such as dendritic cells, are considered to trigger the antitumoral immune response against tumors, such as testicular cancer. Male infertility associated with cancer may be due to endocrine or immunological factors. We investigated possible associations of antigen expression with dendritic cells, histiocytic cells and seminoma stage as well as with impaired spermatogenesis. From 1992 to 1999, 30 patients with seminoma underwent orchiectomy at our center, including 14 who underwent spermiography before orchiectomy. Streptavidin-biotin immunostaining was performed on paraffin -embedded tumor specimens using antibodies against protein S-100 for dendritic cells and CD68-KP1 antigen. Light infiltration by less than 20 dendritic cells and less than 103 CD68+ cells was associated with tumor size greater than 1.5 cm. in 75% and 80% of patients, respectively. Strong infiltration by greater than 20 dendritic cells and greater than 103 CD68+ cells was associated with negative lymph nodes in 86% of patients. Slight infiltration by dendritic cells was observed in 71% of patients with a sperm count of greater than 8.6 million per ml. and in 100% with more than 45% motile sperm (p not significant and 0.02, respectively).

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
