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

Epidermal Growth Factor (EGF) is a protein that stimulates cell growth and differentiation by binding to its receptor epidermal growth factor receptor (EGFR) which triggers ligand-induced d

CD40, a member of the tumor necrosis factor receptor (TNFR) superfamily, plays a pivotal role in regulating immune responses, particularly in activating antigen-presenting cells (APCs) an

PVR (Poliovirus receptor), also known as CD155, is a molecule that plays a dual role in regulating the immune response within the tumor microenvironment. While initially discovered as a r

Cell Signalling · InflammationMAPK Signalling in Inflammatory Cytokine PathwaysMAPK cascades convert receptor engagement into changes in gene expression, and in inflammation they do it in both directi

Cell Signalling · Kinase CascadesMAPK Signaling: The Pathway of Mitogen StimulationThe mitogen-activated protein kinase (MAPK) pathway is one of the most important signalling cascades in biology, conv

Platelet activation plays a pivotal role in hemostasis, the process that stops bleeding and initiates wound healing. Central to this process is the activation of G protein-coupled receptors (GPCRs

Protein kinase B or AKT (PKB) is a serine/threonine kinase. In mammals it is comprised of 3 highly homologous isoforms PKBα (Akt1), PKBβ (Akt2), and PKBγ (Akt3) (Manning and Cantley 2007). AKT
