Regulatory T cells cannot make the cytokine they depend on. FOXP3 represses the Il2 locus, so every Treg lives on IL-2 secreted by the conventional T cells it exists to restrain. That asymmetry expla

The Th1 Pathway In this guide, we will explore the differences between TH1 and TH2 cells, their crucial roles in the immune system, and the contributions of cytokines and transcription f

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

Immunology · HyperinflammationCytokine Storm and Cytokine Release Syndrome: Mechanisms, Triggers and MarkersA cytokine storm is a self-amplifying inflammatory response in which cytokine release drives

In the realm of immunology, CXCL chemokines emerge as fascinating conductors. These small proteins, marked by their CXC motif, wield considerable influence over our immune responses and a ra

Adhesion Molecules Direct cell-cell interactions are maintained and regulated by cell adhesion molecules. The expression of adhesion molecules

The inflammasome is one of the few innate pathways that destroys the cell it activates. A macrophage that assembles NLRP3 has committed to a decision it cannot reverse: a priming signal through TLR4

T cell immunoglobulin and mucin-domain containing-3 (TIM-3) is an immune checkpoint receptor that plays a pivotal role in T cell exhaustion, a state where T cells lose their ability to ef

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

Toll-like receptors are the reason a milligram of endotoxin can kill a mouse. They are the fastest, least discriminating layer of immunity: germline-encoded sensors that read conserved microbial chem

A T-cell engager does not give the T cell an instruction. It gives it an address. A bispecific antibody with one arm on CD3 and the other on a tumour antigen forces two membranes into contact and let

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
