Virus-specific delayed-type hypersensitivity (DTH). Cells mediating lymphocytic choriomeningitis virus-specific DTH reaction in mice.
We had previously shown that the local lymphocytic choriomeningitis virus-induced delayed-type hypersensitivity (DTH) reaction in mice consists of two well delineated phases that are mediated by CD8+ and CD4+ T lymphocytes, respectively. These findings have been confirmed and extended by showing that the first CD8+ cell-dependent part of the response was enhanced by either the presence of CD4+ ...
متن کاملDelayed-type hypersensitivity to influenza virus. Induction of antigen- specific suppressor T cells for delayed-type hypersensitivity to hemagglutinin during influenza virus infection in mice
Mice infected with A/England/939/69 X A/Puerto Rico/8/34 (Rec 31) influenza virus by aerosol develop significantly lower levels of delayed-type hypersensitivity (DTH) to A/Hong Kong/1/68 X A/Puerto Rico/8/34/ (X31) virus compared to uninfected mice. The suppression of DTH to the hemagglutinin appears to be mediated by suppressor T cells which carry Lyt-1 membrane antigen marker, and not by sy s...
متن کاملMembrane fusion mutants of Semliki Forest virus
Previous reports have indicated that the entry of Semliki Forest virus (SFV) into cells depends on a membrane fusion reaction catalyzed by the viral spike glycoproteins and triggered by the low pH prevailing in the endosomal compartment. In this study the in vitro pH-dependent fusion of SFV with nuclease-filled liposomes has been used to select for a new class of virus mutants that have a pH-co...
متن کاملSpecific suppressor T cells for delayed-type hypersensitivity in susceptible mice immunized against cutaneous leishmaniasis.
BALB/c mice injected intravenously with 10(6) or higher doses of formaldehyde-fixed promastigotes (ffp) of Leishmania major developed significantly lower levels of delayed-type hypersensitivity (DTH) compared with uninjected control mice when they were subsequently immunized intradermally with ffp. The suppression of DTH was antigen specific and was also inducible with lethally irradiated proma...
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...
