Twenty years ago, a group of French cell biologists merged two scientific clubs with the aim of bringing together researchers in the fields of Endocytosis and Exocytosis. Founded in 1997, the first annual meeting of the Exocytosis Club was held in 1998. The Endocytosis Club held quarterly meetings from its founding in 1999. The first joint annual meeting of the Exocytosis–Endocytosis Club took place...
Engagement of the B cell receptor (BCR) by surface-tethered antigens (Ag) leads to formation of a synapse that promotes Ag uptake for presentation onto major histocompatibility complex class II (MHCII) molecules. We have highlighted the membrane trafficking events and associated molecular mechanisms involved in Ag extraction and processing at the B cell synapse. MHCII-containing lysosomes are recruited...
Neuroendocrine PC12 cells contain small microvesicles that closely resemble synaptic vesicles in their physical and chemical properties. Two defining characteristics of synaptic vesicles are their homogeneous size and their unique protein composition. Since synaptic vesicles arise by endocytosis from the plasma membrane, nerve terminals and PC12 cells must contain the molecular machinery to sort synaptic...
