Cell Signalling · CytokinesJAK-STAT Signalling: Mechanism, Regulation and InhibitorsJAK-STAT is the shortest route from a cytokine outside the cell to a change in gene transcription — receptor engagem

PD-1 does not switch a T cell off; it moves the threshold. Engagement of PD-1 by PD-L1 recruits a single phosphatase into the immunological synapse, and that one recruitment event is enough to collap

T Cell Types, Activation, Polarization & Function A comprehensive guide to T cells! Introduction T-cells, vital components of the immune system, encompass vari

An agonist antibody does not activate its receptor. It gets held still by something else, and the receptors underneath cluster because they are crowded. That sentence sounds like a technicality and i

Almost all of the TGF-β in a tissue is already there, and almost none of it is active. That single fact reorganises how the pathway should be studied. Unlike most cytokines, TGF-β is deposited into t

Phagocytosis is a subtraction, not a switch. A macrophage engulfs when its activating signals exceed its inhibitory ones, and every awkward result in the myeloid checkpoint field falls out of that on

The angiotensin pathway is a pivotal hormonal system that plays a crucial role in regulating blood pressure and maintaining fluid and electrolyte balance within the body. This complex biochemical

Quick Facts About RamucirumabWhat is Ramucirumab?Ramucirumab is a monoclonal antibody that targets vascular endothelial growth factor receptor 2 (VEGFR-2), inhibiting angiogenesis, a pro

Imagine a world where we can fold the very fabric of life into microscopic machines, guiding the growth of a single neuron with the precision of a master architect. This isn't science fiction; it is

SARS-CoV-2 Background COVID-19 is characterised by a series of biological markers. In some instances, these biomarkers can be used as potenti

Endocrinology · ImmunologyCortisol and the Immune ResponseCortisol is the body’s primary stress hormone — a glucocorticoid released by the adrenal gland that powerfully shapes the immune system. Actin

What is VEGF? Vascular Endothelial Growth Factors (VEGFs) are a group of homodimeric polypeptides, and are master regulators of vascular development, maintenance and a

A T cell does not choose which tissue to defend. The tissue chose it, during priming. A naive T cell has no tropism at all; it acquires one from the dendritic cell that activates it, and the instruct
