Insights

Antibody structure, including oligomerization and Fc receptor binding, is crucial for activating tumor necrosis factor (TNF) receptor superfamily (TNFRSF) signaling. Understanding these factors is key for developing effective TNFRSF-targeting therapies.

Area of Science:

  • Immunology
  • Molecular Biology
  • Biotechnology

Background:

  • Receptors of the tumor necrosis factor (TNF) receptor superfamily (TNFRSF) are critical in cellular signaling.
  • Agonistic antibodies are widely used to stimulate TNFRSF receptors, with CD95 being an early example.
  • Initial in vitro studies highlighted the importance of antibody valency and Fcγ receptor (FcγR) binding for TNFRSF agonistic activity.

Purpose of the Study:

  • To review the critical role of antibody oligomerization and Fcγ receptor (FcγR) binding in TNFRSF receptor activation.
  • To discuss the implications of these factors for the development of therapeutic antibodies targeting TNFRSF.

Main Methods:

  • Review of existing literature on TNFRSF receptor activation by antibodies.
  • Analysis of in vitro and in vivo studies investigating antibody valency, oligomerization, and FcγR interactions.
  • Discussion of current models of TNFRSF receptor activation.

Main Results:

  • Antibodies with higher valency (e.g., IgM) or those prone to aggregation show superior agonistic activity.
  • Binding to Fcγ receptors significantly potentiates TNFRSF receptor signaling.
  • Recent in vivo studies confirm the importance of oligomerization and FcγR binding for therapeutic antibody efficacy.

Conclusions:

  • Antibody oligomerization and FcγR binding are essential for potent TNFRSF receptor stimulation.
  • These structural features are critical considerations for the rational design of therapeutic TNFRSF-targeting antibodies.
  • Further research into these aspects will advance the development of novel immunotherapies.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

B Cell Activation and Differentiation01:24

B Cell Activation and Differentiation

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
