FCR

FCR may stand for the following:

Fc receptor

An Fc receptor is a protein found on the surface of certain cells – including, among others, B lymphocytes, follicular dendritic cells, natural killer cells, macrophages, neutrophils, eosinophils, basophils, human platelets, and mast cells – that contribute to the protective functions of the immune system. Its name is derived from its binding specificity for a part of an antibody known as the Fc (Fragment, crystallizable) region. Fc receptors bind to antibodies that are attached to infected cells or invading pathogens. Their activity stimulates phagocytic or cytotoxic cells to destroy microbes, or infected cells by antibody-mediated phagocytosis or antibody-dependent cell-mediated cytotoxicity. Some viruses such as flaviviruses use Fc receptors to help them infect cells, by a mechanism known as antibody-dependent enhancement of infection.

Classes of Fc receptor

There are several different types of Fc receptors (abbreviated FcR), which are classified based on the type of antibody that they recognize. The Latin letter used to identify a type of antibody is converted into the corresponding Greek letter, which is placed after the 'Fc' part of the name. For example, those that bind the most common class of antibody, IgG, are called Fc-gamma receptors (FcγR), those that bind IgA are called Fc-alpha receptors (FcαR) and those that bind IgE are called Fc-epsilon receptors (FcεR). The classes of FcR's are also distinguished by the cells that express them (macrophages, granulocytes, natural killer cells, T and B cells) and the signalling properties of each receptor.

FCR (company)

FCR is an American outsource provider of call centers. Based in Roseburg, Oregon, FCR was founded in 2005 as Comspan Call Center Services, a division of the communications company, Comspan. After the communications company was bought by a Canadian corporation, the call center was established as its own company by Comspan co-founder John Stadter and business partner Matthew Achak.

FCR also works with insurance companies and other organizations during natural disasters including Hurricane Katrina. FCR maintains a sales office in Seattle, WA and operates call centers throughout Oregon in Roseburg, Grants Pass, Coos Bay, Veneta, Eugene and Independence.

FCR was recognized by Forbes.com as a Company To Watch, citing trends in the call center industry where companies make significant investments in human capital and technology to communicate more effectively with Millennials.
