Conformational change within the extracellular domain of B cell receptor in B cell activation upon antigen binding

open access: yeseLife, 2019
B lymphocytes use B cell receptors (BCRs) to recognize antigens. It is still not clear how BCR transduces antigen-specific physical signals upon binding across cell membrane for the conversion to chemical signals, triggering downstream signaling cascades.

An Introduction to Rule-based Modeling of Immune Receptor Signaling

open access: yes, 2017
Cells process external and internal signals through chemical interactions. Cells that constitute the immune system (e.g., antigen presenting cell, T-cell, B-cell, mast cell) can have different functions (e.g., adaptive memory, inflammatory response ...

Cellular-level versus receptor-level response threshold hierarchies in T-Cell activation [PDF]

open access: yes, 2013
Peptide-MHC (pMHC) ligand engagement by T-cell receptors (TCRs) elicits a variety of cellular responses, some of which require substantially more TCR-mediated stimulation than others.

Antigen Receptor Signals Rescue B Cells from TLR Tolerance [PDF]

open access: yesThe Journal of Immunology, 2009
Abstract Interactions between innate and adaptive immune receptors are critical for an optimal immune response, but the role played by Ag receptors in modulating innate receptor functions is less clear. TLRs are a family of pattern recognition receptors that play crucial roles in detecting microbial pathogens and subsequent ...

Designs of Antigen Structure and Composition for Improved Protein-Based Vaccine Efficacy

open access: yesFrontiers in Immunology, 2020
Today, vaccinologists have come to understand that the hallmark of any protective immune response is the antigen. However, it is not the whole antigen that dictates the immune response, but rather the various parts comprising the whole that are capable ...

Immunotherapy in hepatocellular carcinoma: the complex interface between inflammation, fibrosis, and the immune response. [PDF]

open access: yes, 2019
Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths worldwide and confers a poor prognosis. Beyond standard systemic therapy with multikinase inhibitors, recent studies demonstrate the potential for robust and durable responses ...

Self-antigen recognition by follicular lymphoma B-cell receptors [PDF]

open access: yesBlood, 2012
Abstract Follicular lymphoma is a monoclonal B-cell malignancy with each patient's tumor expressing a unique cell surface immunoglobulin (Ig), or B-cell receptor (BCR), that can potentially recognize antigens and/or transduce signals into the tumor cell.

Inhibitory B cell co-receptors and autoimmune diseases

open access: yesImmunological Medicine, 2019
B cells express various inhibitory co-receptors including CD22 (also known as Siglec-2), Siglec-10 (Siglec-G in mice), CD72, LILRB (PIR-B in mice) and FcγRIIB that contain immunoreceptor tyrosine-based inhibition motifs (ITIMs) in the cytoplasmic region ...

Understanding the Mechanisms of Resistance to CAR T-Cell Therapy in Malignancies

open access: yesFrontiers in Oncology, 2019
Taking advantage of the immune system to exert an antitumor effect is currently a novel approach in cancer therapy. Adoptive transfer of T cells engineered to express chimeric antigen receptors (CARs) targeting a desired antigen has shown extraordinary ...

The Symmetrical Immune Network Theory and a New HIV Vaccine Concept [PDF]

open access: yes, 2010
The symmetrical immune network theory is based on Jerne’s network hypothesis. An improved version of the theory is presented. The theory is characterized by symmetrical stimulatory, inhibitory and killing interactions between idiotypic and ...
