Virus-induced delayed-type hypersensitivity reaction is sequentially mediated by CD8+ and CD4+ T lymphocytes.
After subcutaneous inoculation into the hind foot of a mouse, the lymphocytic choriomeningitis (LCM) virus multiplies locally, attaining 10(7)-10(8) mouse infectious units per g of tissue; elimination commences around day 7. About 1 day earlier, the foot begins to swell, which is regarded as a delayed-type hypersensitivity (DTH) reaction. To answer the question of whether the local inflammatory...
متن کاملRole of IL-16 in delayed-type hypersensitivity reaction.
Interleukin (IL)-16 is a chemoattractant cytokine for CD4(+) leukocytes. Because delayed-type hypersensitivity (DTH) reaction is mediated by T helper 1 (Th1) cells and CD4(+) T cells can be chemoattracted by IL-16, we have investigated the involvement of IL-16 in the DTH reaction. Immunohistochemical analysis revealed the IL-16 expression in infiltrating cells and epithelial cells in the DTH fo...
متن کاملPharmacological activities of saponin-containing fraction derived from Gleditsia caspica Desf. methanolic fruit extract
Phytochemical investigations of Gleditsia fruits have revealed the presence of triterpenoidal saponins. These saponins proved to possess anti-inflammatory and anti-allergic activities. The present study was undertaken to evaluate the anti-inflammatory, analgesic and antipyretic activities of the saponin fraction derived from the methanolic extract of Gleditsia caspica fruits. The fraction at 31...
متن کاملDelayed-type hypersensitivity reaction to ethambutol and isoniazid.
A 24-year-old woman had recently started antitubercular therapy with isoniazid, ethambutol and rifampicin. This therapy was discontinued 2 weeks later due to an itchy, desquamative, erythematous, papular rash, with painful crusts and excoriations, spreading from the face and hands to the rest of the body. 5 days after withdrawal of all drugs, widespread desquamation and exfoliation with predile...
متن کاملLow Concentrations of Flavonoid - Rich Fraction of Shallot Extract Induce Delayed - Type Hypersensitivity and TH1 Cytokine IFN-gamma Expression in Balb/C Mice
Flavonoids are potentially immunomodulatory factors and it may be inferred that these phytochemicals contribute to immunomodulatory properties of the Allium family. In the present study, we investigated the potential mechanism underlying the immunomodulatory effect of shallot and its ethyl acetate (EA) fraction as flavonoid-rich sources. Ex vivo, effects of a hydroalcoholic extract of shallot, ...
