Pneumocystis carinii glycoprotein A binds macrophage mannose receptors

HIV impairs alveolar macrophage mannose receptor function against Pneumocystis carinii.

Molecular characterization of mouse Pneumocystis carinii surface glycoprotein A.

Since the mouse offers an easily manipulated experimental animal model for the study of the immunopathogenesis of pneumonia caused by the opportunist Pneumocystis carinii, we cloned and characterized cDNAs encoding an abundant, immunogenic surface antigen termed glycoprotein A (gpA) from mouse P. carinii. A cDNA library was constructed in bacteriophage lambda gt11 from P. carinii-infected mouse...

Type-II major-surface-glycoprotein family of Pneumocystis carinii.

Pneumocystis carinii are coated by abundant surface proteins, named MSGs for major surface glycoproteins, that undergo antigenic variation. There are many MSG genes on the chromosomes but the MSG expression site is restricted to a unique site called type-I UCS, and silent MSG genes can be translocated to the expression site by DNA recombination. We have reported previously the existence of alte...

Pneumocystis carinii.

Although Giemsa staining has been routinely used for the detection of trophozoites and intracystic bodies in smears of bronchoalveolar lavage fluid (BAL) from patients with Pneumocystis cariniipneumonia, it does not normally stain the cyst wall. For detection ofthe cysts other stains such as toluidine Blue 'O' and methenamine silver must be used as well. Sulphation of smears before staining wit...

Absence of the macrophage mannose receptor in mice does not increase susceptibility to Pneumocystis carinii infection in vivo.

Host defense against the opportunistic pathogen Pneumocystis carinii requires functional interactions of many cell types. Alveolar macrophages are presumed to be a vital host cell in the clearance of P. carinii, and the mechanisms of this interaction have come under scrutiny. The macrophage mannose receptor is believed to play an important role as a receptor involved in the binding and phagocyt...
