Prior Fc receptor activation primes macrophages for increased sensitivity to IgG via long-term and short-term mechanisms.

Macrophages measure the "eat-me" signal immunoglobulin G (IgG) to identify targets for phagocytosis. We tested whether prior encounters with IgG influence macrophage appetite. IgG is recognized by the Fc receptor.

Prior Fc Receptor activation primes macrophages for increased sensitivity to IgG via long term and short term mechanisms.

Macrophages measure the 'eat-me' signal IgG to identify targets for phagocytosis. We wondered if prior encounters with IgG influence macrophage appetite. IgG is recognized by the Fc Receptor.
