A general cytoplasmic signaling mechanism for the novel functions of diverse alpha protocadherins in cortical neuron migration and actin cytoskeletal dynamics as well as dendrite morphogenesis in the brain.
New insights into the mechanism responsible for the nucleation of branches on networks of actin filaments shed light on a process that is essential for eukaryotic cell motility and endocytosis.

Intersectin2 deficiency is associated with impaired humoral responses to viral infection and B-cell-intrisic defects in germinal centre formation, resulting from the reduced ability of intersectin2-KO B cells to establish cognate interactions with helper T cells.

Arp2/3 complex-mediated actin polymerization shapes how B lymphocytes probe the surface of antigen-presenting cells, promotes coalescence of B cell receptor (BCR) microclusters, amplifies BCR signaling, and enhances B cell activation.

A 3D bone marrow niche that reproduces megakaryocyte differentiation and ex vivo platelet production from hematopoietic progenitors and iPSCs of thrombocytopenic patients predicts individual response to Eltrombopag accurately.
The immunoglobulin superfamily cell surface protein Sticks and Stones is a binding partner for the Lar Drosophila receptor tyrosine phosphatase that mediates Lar's developmental functions at the larval neuromuscular junction, mushroom body, and adult optic lobe.
A peptide from PCARE achieves >100-fold binding specificity for the EVH1 domain of ENAH, a protein important for metastasis, using a conformational shift mechanism unavailable to ENAH's closely related paralogs VASP and EVL.
