Immune Regulation in COVID-19: Immunomodulatory Mechanisms against SARS-CoV-2 Infection What is COVID-19?

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

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

What does the COVID-19 Rapid POC CE-IVD Test detect? The test detects the presence of patient-generated antibodies against spike protein, the virus which causes the disease COVID-19. The tes

Dozens of cytokines converge on four kinases and seven transcription factors. That compression is the problem JAK–STAT has to solve, and it is why this map is drawn as receptor, kinase and STAT colum

Key Facts About SacituzumabWhat is Sacituzumab?Sacituzumab is an antibody-drug conjugate (ADC) that targets the tumor-associated antigen Trop-2, used to treat various cancers, including

Signal 1 tells a T cell what it is looking at; signal 2 tells it whether to care. The same peptide–MHC engagement that launches a productive effector response can just as easily install an anergy pro

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

Bone Morphogenetic Proteins (BMP) were first discovered in the 1960s by Dr.Marshall Urist, an orthopaedic surgeon at UCLA (Urist 1965). BMPs are classically associated with their roles in limb

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

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

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
