Initiation of HIV therapy [PDF]

open access: yes, 2010
In this paper, we numerically show that the dynamics of the HIV system is sensitive to both the initial condition and the system parameters. These phenomena imply that the system is chaotic and exhibits a bifurcation behavior.

Variant surface glycoprotein density defines an immune evasion threshold for African trypanosomes undergoing antigenic variation

open access: yesNature Communications, 2017
Trypanosoma brucei evades the host immune system through replacement of a variant surface glycoprotein (VSG) coat. Here, the authors show that VSG replacement takes several days to complete, and the parasite is vulnerable to the host immune system for a ...

CCCTC-Binding Factor Locks Premature IgH Germline Transcription and Restrains Class Switch Recombination

open access: yesFrontiers in Immunology, 2017
In response to antigenic stimulation B cells undergo class switch recombination (CSR) at the immunoglobulin heavy chain (IgH) to replace the primary IgM/IgD isotypes by IgG, IgE, or IgA.

Inherited immunodeficiencies associated with proximal and distal defects in T cell receptor signaling and co-signaling

open access: yesBiomedical Journal, 2022
T lymphocytes are central cells of adaptive immunity. Activation of T lymphocytes by the antigen receptor of T cells (TCR) and co-stimulatory molecules involve specific signaling components and cascades.

Regulated progression of B lymphocyte differentiation from cultured fetal liver. [PDF]

open access: yes, 1987
Lymphoid fetal liver cultures (LFLC) are long-term, nontransformed cultures of early B lymphoid lineage cells which appear developmentally blocked at the pre-B stage in vitro.

Lymphocytic Adenohypophysitis and Lymphocytic Infundibuloneurohypophysitis.

open access: yesEndocrine Journal, 1997
One hundred and twenty-four cases of lymphocytic adenohypophysitis have been reported since 1962. Nearly 60% of the cases in women involved inset of the disease in relation to pregnancy. Headache and visual field defects were the most frequent symptoms.

A novel method to allow noninvasive, longitudinal imaging of the murine immune system in vivo [PDF]

open access: yes, 2012
In vivo imaging has revolutionized understanding of the spatiotemporal complexity that subserves the generation of successful effector and regulatory immune responses.

CD4 T lymphocyte autophagy is upregulated in the salivary glands of primary Sjögren’s syndrome patients and correlates with focus score and disease activity [PDF]

open access: yes, 2017
Background: Primary Sjögren’s syndrome (pSS) is a common chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands and peripheral lymphocyte perturbation.

Loss of RASGRP1 in humans impairs T‐cell expansion leading to Epstein‐Barr virus susceptibility

open access: yesEMBO Molecular Medicine, 2018
Inherited CTPS1, CD27, and CD70 deficiencies in humans have revealed key factors of T‐lymphocyte expansion, a critical prerequisite for an efficient immunity to Epstein–Barr virus (EBV) infection.

Tuning of in vivo cognate B-T cell interactions by Intersectin 2 is required for effective anti-viral B cell immunity

open access: yeseLife, 2018
Wiskott-Aldrich syndrome (WAS) is an immune pathology associated with mutations in WAS protein (WASp) or in WASp interacting protein (WIP). Together with the small GTPase Cdc42 and other effectors, these proteins participate in the remodelling of the ...
