Sensitization or tolerance to Mycobacterium leprae antigen by route of injection

Genetic control of delayed type hypersensitivity to Mycobacterium leprae antigen.

The mechanism of genetic control of Mycobacterium leprae-specific delayed type hypersensitivity (DTH) in mice was investigated in terms of footpad swelling response. Studies with various congenic and recombinant inbred strains of mouse revealed that M. leprae-specific DTH was controlled by genes within the I-A subregion. The footpad swelling response showed an antigen-specific pattern, revealin...

Characterization of a Mycobacterium leprae antigen related to the secreted Mycobacterium tuberculosis protein MPT32.

Secreted proteins may serve as major targets in the immune response to mycobacteria. To identify potentially secreted Mycobacterium leprae antigens, antisera specific for culture filtrate proteins of Mycobacterium tuberculosis were used to screen a panel of recombinant antigens selected previously by leprosy patient sera. Four potentially secreted antigens were identified by this approach, and ...

leprae antigen T 5 . T - cell - stimulatory capacity of Mycobacterium

Presence of human T-cell responses to the Mycobacterium leprae 45-kilodalton antigen reflects infection with or exposure to M. leprae.

The ability of the 45-kDa serine-rich Mycobacterium leprae antigen to stimulate peripheral blood mononuclear cell (PBMC) proliferation and gamma interferon (IFN-gamma) production was measured in leprosy patients, household contacts, and healthy controls from areas of endemicity in Mexico. Almost all the tuberculoid leprosy patients gave strong PBMC proliferation responses to the M. leprae 45-kD...

Structure of Mycobacterium leprae.

Introduction : why study structure? Information about the structure of M. leprae may be obtained by microscopy (especially electron miscroscopy) and other physical techniques . There is active development of such techniques , but at present the information they can give about structures as complex as a bac­ terium is l imited . To obtain a detailed knowledge of the molecular composition and con...
