Fc effector functions in RNA viral infections: mechanisms of antiviral immunity and implications for vaccine design [PDF]

open access: yesFrontiers in Immunology
Neutralizing antibodies (NAbs) have long been the principal correlate of antiviral protection. Evidence now indicates that antibody Fc-mediated effector functions play indispensable and context-dependent roles in antiviral immunity.

Fc receptors act as innate immune receptors during infection?

open access: yesFrontiers in Immunology, 2023
Innate immunity constitutes the first nonspecific immunological line of defense against infection. In this response, a variety of mechanisms are activated: the complement system, phagocytosis, and the inflammatory response.

Biophysical Evaluation of Rhesus Macaque Fc Gamma Receptors Reveals Similar IgG Fc Glycoform Preferences to Human Receptors

open access: yesFrontiers in Immunology, 2021
Rhesus macaques are a common non-human primate model used in the evaluation of human monoclonal antibodies, molecules whose effector functions depend on a conserved N-linked glycan in the Fc region.

Fc-engineered antibodies with immune effector functions completely abolished.

open access: yesPLoS ONE, 2021
Elimination of the binding of immunoglobulin Fc to Fc gamma receptors (FcγR) is highly desirable for the avoidance of unwanted inflammatory responses to therapeutic antibodies and fusion proteins.

The Diverse Functions of the Ubiquitous Fcγ Receptors and Their Unique Constituent, FcRγ Subunit

open access: yesPathogens, 2020
Fc gamma receptors (FcγRs) are widely expressed on a variety of immune cells and play a myriad of regulatory roles in the immune system because of their structural diversity.

Fc RECEPTORS AND THEIR INTERACTIONS WITH IMMUNOGLOBULINS [PDF]

open access: yesAnnual Review of Cell and Developmental Biology, 1996
▪ Abstract  Receptors for the Fc domain of immunoglobulins play an important role in immune defense. There are two well-defined functional classes of mammalian receptors. One class of receptors transports immunoglobulins across epithelial tissues to their main sites of action.

Human mast cell activation through Fc receptors and Toll-like receptors

open access: yesAllergology International, 2004
Mast cells express high-affinity IgE receptors (FcεRI) on their surface and can be activated to secrete a variety of biologically active mediators by cross-linking of receptor-bound IgE.

Receptor for Fc on the Surfaces of Schistosomes [PDF]

open access: yesInfection and Immunity, 2001
ABSTRACTSchistosoma mansonimasks its surface with adsorbed host proteins including erythrocyte antigens, immunoglobulins, major histocompatibility complex class I, and β2-microglobulin (β2m), presumably as a means of avoiding host immune responses. How this is accomplished has not been explained.

Pentraxins and Fc Receptor-Mediated Immune Responses

open access: yesFrontiers in Immunology, 2018
C-reactive protein (CRP) is a member of the pentraxin family of proteins. These proteins are highly conserved over the course of evolution being present as far back as 250 million years ago.

Multimerization strategies for efficient production and purification of highly active synthetic cytokine receptor ligands.

open access: yesPLoS ONE, 2020
Cytokine signaling is transmitted by cell surface receptors which act as natural biological switches to control cellular functions such as immune reactions.
