T1  - Expression of T-cell-associated serine proteinase-1 during murine Leishmania major infection correlates with susceptibility to disease
N2  - The expression of T-cell-associated serine proteinase 1 (MTSP-1) in vivo during Leishmania major infection was analyzed in genetically resistant C57BL/6 mice and in genetically susceptible BALB/c mice. Using a monoclonal antibody as well as an RNA probe specific for MTSP-1 to stain tissue sections, we found T cells expressing MTSP-1 in skin lesions and spleens of mice of both strains. In skin lesions, MTSP-1-positive T cells could be detected as early as 3 days after infection. Most importantly, the frequency of T cells expressing MTSP-1 was significantly higher in susceptible BALB/c mice than in resistant C57BL/6 mice. These findings suggest that MTSP-1 is associated with disease-promoting T cells and that it may be an effector molecule involved in the pathogenesis of cutaneous leishmaniasis.

T1  - Simultaneous demonstration of two antigens with immunogold-silver staining and immunoenzymatic labeling
N2  - A novel technique for independent and simultaneous labeling of two antigens expressed on individual cells (referred to as mixed labeling) is presented. The staining procedure combined three-step (streptavidin-biotin) immunogold-silver staining with three-step immunoenzymatic labeling. To ensure both high specificity and high sensitivity, particular emphasis was placed on designing a protocol that avoids immunological crossreactivity between the antibody reagents and overlapping of the final color products. Two examples for usage of this mixed labeling technique are described: lymphocyte subpopulations were identified in inflammatory lesions of human skin and infected host cells were characterized in the skin of mice infected with the obligatory intracellular parasite Leishmania major, a cause of human cutaneous leishmaniasis.
