Pathogenesis an immunopathology of leishmaniasis

Immunopathology of leishmaniasis: an update.

Leishmaniasis represents a severe, increasing, public health problem. The perspective of its control is highly dependent on research progress, on therapeutic manipulations of the immune system, and on vaccine development. There is a correlation between the clinical outcome of Leishmania infection and the cytokine response profile. While a protective immune response against Leishmania has been c...

Immunopathology of primary hypophysitis: implications for pathogenesis.

The etiology of primary hypophysitis is still not fully elucidated. Histologically, primary hypophysitis includes three different main subtypes: lymphocytic (LYH), granulomatous (GRH), and xanthomatous (XH) hypophysitis. Clinical and laboratory findings suggest an autoimmune basis in primary hypophysitis. Controversy still exists about the composition of the inflammatory infiltrate and the rele...

Immunopathology of autoantibody-associated encephalitides: clues for pathogenesis.

Classical paraneoplastic encephalitis syndromes with 'onconeural' antibodies directed to intracellular antigens, and the recently described paraneoplastic or non-paraneoplastic encephalitides and antibodies against both neural surface antigens (voltage-gated potassium channel-complexes, N-methyl-d-aspartate receptors) and intracellular antigens (glutamic acid decarboxylase-65), constitute an in...

Suppression of pathogenesis in cutaneous leishmaniasis by UV irradiation.

The effects of suberythematous levels of UV-B radiation on the development of of cutaneous leishmaniasis were studied in B10.129(10M) mice. Doses of 15 mJ cm-2 UV-B applied locally to the injection site suppressed the development of skin lesions after the inoculation of Leishmania major promastigotes. The primary targets of UV-B radiation appeared to be host cells and not leishmanial parasites,...
