Rejuvenating conventional dendritic cells and T follicular helper cell formation after vaccination

eLife, 2020
Germinal centres (GCs) are T follicular helper cell (Tfh)-dependent structures that form in response to vaccination, producing long-lived antibody secreting plasma cells and memory B cells that protect against subsequent infection. With advancing age the

Sensitivity of activated human lymphocytes to cyclosporine and its metabolites [PDF]

, 1988
Alloreactive T cells generated as clones from mixed lymphocyte cultures, or propagated from heart or liver transplant biopsies, were tested for secondary proliferation measured in the primed lymphocyte test in the presence of Cyclosporine A and ...

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

Nature 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

Nature 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 ...

Use of Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios in COVID-19

Journal of Clinical Medicine Research, 2020
Background As the pandemic of coronavirus disease 2019 (COVID-19) continues, prognostic markers are now being identified. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are easily accessible values that have been known to

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]

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

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

Frontiers 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

Biomedical 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.
