In the Thymus, Co-stimulation Kills(Post)
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
No Cytokine on This Pathway Touches Bone(Post)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
The Lenti Viral Vector System: A New Way to Deliver Genetic Therapies(Post)Gene Delivery · Viral VectorsLentiviral Vectors: Design, Production and Use in Gene DeliveryLentiviral vectors integrate their cargo into the host genome and transduce dividing and non-dividing cells
IQGAP1 signaling review(Post)IQGAP1: IQ-motif containing GTPase-activating-like protein-1 reviewIQ motif-containing GTPase-activating-like protein-1 (IQGAP1) is a 190 KDa protein that belongs to a conserved family of sc
Sci-Hub: Your Proxy to Unrestricted Knowledge(Post)Introduction to Sci-Hub In the realm of science and academia, one name has been echoing in every corner of the globe, Sci-Hub. Created by Alexandra Elbakyan, a Kazakhstani computer scientist

Anti-Angiogenics Do Not Starve Tumours. They Open Them.(Post)Anti-angiogenic therapy does not work by starving tumours, and the trials that assumed it did are the reason the field spent a decade disappointed. Cutting off the blood supply was the original pitch
One Ligand, Two Receptors, Opposite Jobs: TNFR1 vs TNFR2(Post)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
Binding Is the Easy Part(Post)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
6 Schritte: ELISA Blockierpuffer nach Detektionschemie wählen(Post)Der richtige Startpunkt für die meisten ELISA‑Protokolle ist Magermilchpulver (NFDM) in TBST für HRP‑basierte Assays ohne Phospho‑Ziele, typischerweise in der gängigen Konzentrationsspanne. Bei St
Th17 and IL-23: Why Blocking IL-17 Sometimes Backfires(Post)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
One Integrin Chain, Two Partners, Brain or Gut(Post)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
IgE and Mast Cells: The Cell Is Armed in Advance(Post)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

Your Th2 Phenotype Might Not Be a T Cell(Post)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
TNF cytokines and their Receptors(Post)The human body is a complex and intricate system where various components work together to maintain health and combat potential threats. Among these essential players are the TNF cyt
Two Asthma Drugs, Opposite Eosinophil Counts, Both Working(Post)Two asthma biologics have opposite effects on the blood eosinophil count, and both of them work. Mepolizumab empties the eosinophil compartment; dupilumab can transiently raise it. If that seems cont
CAR-T Cell Signalling Pathway: Costimulation, Output and Assays(Post)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
PD-1/PD-L1 Checkpoint Signalling: Pathway, Function and Assays(Post)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
