NanoCellBiology of Secretion

BHANU P. JENA, PHD, DSc, is the George E. Palade University Professor and Distinguished Professor of Physiology at Wayne State University School of Medicine, Detroit, Michigan. In addition,

Understanding live cells at the single molecule level is the most important and single major challenge facing biology and medicine today. Over the past 15 years, there has been a renewed understanding of living cells at the molecular level. Atomic Force Microscopy, Laser Force Microscopy, single secretory vesicle patch clamp studies, highresolution electron microscopy, and x-ray diffraction, are some of the tools now being used to unravel the intricacies of a living cell at the molecular level. Opening with an explanation of Materials and Methods, NanoCellBiology then moves through discussions of porosome discovery, calcium and SNARE-induced fusion, and vesicle swelling before winding up in a final chapter of conclusions and future studies. Succinctly packaged as SpringerBrief, this book is a must for those studying or conducting research in cell biology, biochemistry or nanobiology/nanotechnology. This book will be invaluable to faculty & graduate students involved in Nano Courses; Cell Biology Courses; Biophysics Courses; and Biochemistry Courses as well as practicing Cell Biologists, Biochemists and BioPhysicists.
