V-domain Ig suppressor of T cell activation (VISTA) is an emerging immune checkpoint receptor that plays a key role in suppressing T cell activity within the tumor microenvironment (TME).

A macrophage does not decide to eat; it counts votes. Every particle it touches carries a mixture of pro-phagocytic and inhibitory ligands, and engulfment follows only when the activating tally clear

The germinal centre is where antibody quality is made. A naive B cell that binds antigen does not become a source of protective, high-affinity IgG by accident. It passes through a tightly choreograph

Imagine a microscopic sniper, capable of delivering a lethal blow to a single cancer cell while leaving its healthy neighbors virtually untouched. This is the promise of targeted alpha therapy, a rev

Tocilizumab reverses cytokine release syndrome within hours, and it never touches the cell that started it. That sentence contains the whole mechanism. The trigger is a T cell — engaged by a CAR, a b

Understanding Lag-3, Tim-3, and TIGIT: Key Players in T Cell RegulationThe immune system's ability to regulate T cell responses is crucial for maintaining homeostasis and combating diseases such as ca

In the periphery, co-stimulation rescues a T cell. In the thymus, the same molecules kill it. A peripheral T cell that engages its receptor without CD80 and CD86 becomes anergic; engage them and it r

For decades, the fight against cancer has been a story of incremental gains. But what if we could fundamentally shift the battlefield, turning the body's own immune system into a precision-guided weap

Double-stranded DNA in the cytosol is always a mistake. A virus has uncoated, a mitochondrion has ruptured, a micronucleus has burst, or a chromosome has been broken and left unrepaired. cGAS treats

QUICK ANSWER A researcher ran a competitive 2,3-bisphosphoglycerate (2,3-BPG) ELISA on red blood cell (RBC) lysate. The standard curve was textbook, yet every lysate sample read at the

PD-1 gets the attention, but it is one brake among many — and the others do not work the same way. The co-inhibitory receptors are routinely drawn as interchangeable stop signs on a T cell. They are

Blocking TNF cures rheumatoid arthritis in some patients and triggers demyelination in others. That is not a dosing problem, and it is not a patient-selection problem. It is the direct consequence of

If your knockout showed a type 2 phenotype and you attributed it to Th2 cells, there is a reasonable chance you were looking at something else. Innate lymphoid cells run T-bet, GATA3 and RORγt — not

Low-dose IL-2 expands regulatory T cells. High-dose IL-2 expands the cells they exist to restrain. Same cytokine, same receptor family, opposite clinical intent — and the explanation is a receptor su

Regulatory T cells (Tregs) play a crucial role in maintaining immune balance by suppressing excessive immune responses that could lead to tissue damage. However, in the context of cancer,

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

Most immunology is written as though a T cell must first be told what to look for. Three lineages did not read that memo. γδ T cells, invariant NKT cells and MAIT cells leave the thymus with their ef

The antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C
