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 ...

Structure of mammalian Mediator complex reveals Tail module architecture and interaction with a conserved core

open access: yesNature Communications, 2021
The Mediator complex regulates RNA polymerase II transcription in all eukaryotes. The mammalian Mediator cryo-EM structure reveals the architecture of previously unresolved Tail module and suggests its regulatory role in the complex conformation and ...

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.

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.

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.

Cardiosphere-derived cells suppress allogeneic lymphocytes by production of PGE2 acting via the EP4 receptor [PDF]

open access: yes, 2018
derived cells (CDCs) are a cardiac progenitor cell population, which have been shown to possess cardiac regenerative properties and can improve heart function in a variety of cardiac diseases. Studies in large animal models have predominantly focussed on

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 ...
