CD205: Relevant in Antigen Presentation, Apoptosis, and Tolerance

Overview

CD205, previously known as DEC-205, is a C-type lectin that belongs to the family of macrophage mannose receptors (MMR). In humans, it is highly expressed on myeloid blood dendritic cells (DC) and monocytes; at medium levels on B cells and low levels on NK cells, plasmatoid DC and T cells. Cortical epithelial cells also express CD205. Mice have a narrower CD205 expression profile on leukocytes. Furthermore, expression is higher on mature DC; having carried out an endocytic function on immature DC. While the precise ligand for CD205 has not been defined yet, it has been established that it is a receptor for dying cells, a function that may be important in thymic and peripheral tolerance.

Human

Antibodies to human CD205 (MCA4755, clone DEC205) are produced by Bio-Rad in a range of formats including RPE for flow cytometry. Purified and low endotoxin versions of clone DEC205 are additionally suitable for immunoprecipitation and staining frozen histology sections.

Mouse

Anti mouse CD205 (MCA949, clone NLDC-145) has not only been conjugated to the traditional flow label FITC but also the higher performance Alexa Fluor® 488, Alexa Fluor ® 647, and Alexa Fluor ® 700. Clone NLDC-145 in supernatant form can be used for staining frozen sections.

Bovine

In addition to anti human and mouse CD205, Bio-Rad offers bovine specific CD205 (MCA1651, clone CC98). FITC labelled antibody is available for flow work. For immunoprecipitation and staining frozen sections a purified version is available. Anti-CD205 antibodies produced by clone CC98 are also able to reveal CD205 on sheep leukocytes.
