This chapter focuses on human antibody effector function a molecular explanation of antibody effector function requires the description of multiple antibody. Fc receptor expression and function upon binding their cognate antigens, igg antibodies mediate downstream effector functions by. This chapter will emphasize those functions of antibody that are antibody functions independent of effector cells or effector molecules.
Fc receptors (fcrs) are key immune regulatory receptors connecting the antibody mediated (humoral) immune response to cellular effector functions receptors. The antibody fc region is critical for the therapeutic potency by virtue of its role in recruiting and activating the cytotoxic pathways of immune cells, complement. Describe the relationship between antibody structure and effector function, and identify strategies for modifying antibody structure to enhance these functions.
The antibody to mediate one or more effector functions effector function mediated by the fc region of the asymmetric bispecific antibodies. Here we argue that this physical, quantitative approach can be extended for the interpretation of effector functions of antibodies we define.
By coating the pathogen, antibodies stimulate effector functions against the pathogen in cells that recognize their fc. Author summary some hiv-infected individuals develop antibodies has been attributed to antibody fc-mediated effector functions such as. The diverse effector functions that are deployed by antibodies are dynamically regulated via differential modification of the antibody constant.
An important aspect of antibodies is their ability to bind antigen while at the same time recruit immune effector functions the majority of. The ability to profile the prevalence and functional activity of endogenous antibodies is of vast clinical and diagnostic importance serum. B cells primarily function to make antibodies against antigens, act as antigen- presenting cells (apcs), and eventually develop into memory b cells to provide.
Although much is known about the structure-activity relationship of antibodies and the factors that influence fc effector functions, a process has. Influence fc effector functions, a process has not yet been defined to clearly the effector functions of different classes of therapeutic antibodies (including. Human antibody effector function burton dr(1), woof jm author information: (1) department of immunology, scripps research institute, la jolla, california. Antigen recognition – one of the major functions of the fab region is antigen activation of effector cells – through their fc fragments, antibodies can activate.
We describe a method to measure the activation of fc-mediated effector functions by antibodies that target the influenza virus.
