Scientists at CSIR-Centre for Cellular and Molecular Biology (CCMB) discovered how white blood cells adapt their skeletons to fight pathogens. The study was published in Nature Structural & Molecular Biology. Cell shape depends on a dense, branched actin network near the membrane. Actin molecules push the membrane and create new meshworks for movement. A protein called SPIN90 regulates actin monomers and pairs with the Arp2/3 complex. Together, they grow new actin filaments in two directions about 150° apart. These filaments act as scaffolds to form branched actin mesh, reshaping the cell and aiding motility. This discovery explains rapid immune response and has implications for cancer, immune disorders, and wound healing.
