Fibroblasts, essential components of connective tissues, play vital roles in maintaining tissue structure and function. Their remarkable ability to produce and organize the extracellular matrix

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

Two drugs aimed at the same axis can give opposite results in the same disease. Blocking IL-23p19 is highly effective in psoriasis and works in Crohn’s disease. Blocking IL-17A directly is highly eff

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

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

A chemokine gradient does not move a leukocyte anywhere. It only tells one that has already stopped which way to go. That sentence is the whole map. Trafficking is a four-step cascade and the steps a

Almost any inflammatory phenotype in a mouse can be assigned to a cytokine by taking that cytokine away. Neutralisation is the most direct causal test immunology has: inject a functional-grade antibo

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

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

An antibody–drug conjugate is not a targeted drug. It is a delivery problem with an antibody bolted to the front of it. Binding is the easy part, and it is almost never the part that fails. What deci

The mast cell is loaded long before the allergen arrives. IgE bound to FcεRIα is not waiting to be recruited the way an antibody waits for antigen in a serum assay — it is already installed on the ce

Not one immune cytokine on this pathway touches bone. TNF, IL-1β, IL-6 and IL-17A all act on osteoblasts, osteocytes and synovial fibroblasts, and it is those stromal cells that decide between RANKL

A chimeric antigen receptor is a synthetic protein wired into a real signalling pathway. The extracellular half is an antibody fragment; everything below the membrane is borrowed from the T-cell rece
