Characterization of cellular infiltrates and cytokine production during the expression phase of the anticryptococcal delayed-type hypersensitivity response.
Cryptococcosis, an increasingly important opportunistic infection caused by the encapsulated yeast-like organism Cryptococcus neoformans, is limited by an anticryptococcal cell-mediated immune (CMI) response. Gaining a thorough understanding of the complex anticryptococcal CMI response is essential for developing means of controlling infections with C. neoformans. The murine cryptococcosis mode...

THE EFFECT OF ASCORBIC ACID ON BLOOD HISTAMINE LEVEL AND DELAYED-TYPE HYPERSENSITIVITY IN GUINEA PIGS
The effect of ascorbic acid on blood histamine level and delayed-type hypersensitivity was studied in thirty male guinea pigs. Animals were sensitized to B.C.G., trichophytin and mallein during the first four weeks. The diet was ad libitum during this period. After this "sensitization period" animals w er e tested intradermally with tuberculin, trichophytin and mallein. The number and diam...
متن کاملA stable form of delayed-type hypersensitivity
An antigen dose below the level needed to provoke an antibody response produces in mice a persistent, but minor degree of delayed-type hypersensitivity (dth) to sheep red blood cells. The DTH is unstable. It is erased by larger doses of antigen and cannot be built upon by further antigenic stimulation. The much higher levels of DTH resulting from immunization under the modulating influence of c...
متن کاملIntestinal amoebiasis: delayed-type hypersensitivity response in mice.
Delayed-type hypersensitive (DTH) response was evaluated in C3H/HeJ mice intestinally infected with Entamoeba histolytica. Infected and non-infected control mice were challenged with amoebic antigen on day 5, 10, 15, 20, 25, 30, 40, 50, and 60 post-infection. Maximum footpad swelling was observed after 24 hours of the challenge. The E. histolytica-infected mice exhibited a DTH response on day 5...
