In the past several years, there has been an exciting body of new research that links impairments in the expression or function of neuronal chloride transporters to a growing number of diseases spanning from autism to brain aging. This book introduces the core concepts and highlights the recent advances in understanding the physiology and pathophysiology of the KCC and NKCC families of neuronal chloride transporters. Neuronal chloride transporter biology is reviewed, including roles in setting the transmembrane chloride gradient and the chloride transport-independent functions, such as regulating excitatory neurotransmission. Chapters are also dedicated to addressing the structure, post-translational modification, membrane trafficking, and protein interaction partners of neuronal chloride transporters, as well as the genetic and environmental factors that regulate their expression in neurons and the novel therapeutic approaches that target neuronal chloride transporters to treat neurological diseases. This new volume will provide readers with an up-to-date summary of the recent advances in neuronal chloride transporter research, with particular emphasis on some of the key emerging topics in the field.

Dr. Tang is a Simons postdoctoral scholar at the Massachusetts Institute of Technology in Cambridge. As part of The Whitehead Institute for Biomedical Research, he is a member of Dr. Rudolf Jaenisch’s lab, a world-renowned pioneer of transgenic science and a Whitehead founding member. His current research focus is the identification of drugs and chemical compounds that increase KCC2 expression, a neuronal chloride transporter implicated in Rett syndrome, a severe autism spectrum disorder primarily affecting young girls. He is known in the neurodevelopment field for his seminal work with human stem cell-derived neurons linking a reduction in chloride transporter expression to Rett syndrome pathogenesis, providing compelling evidence that disruptions in neuronal chloride transporters and excitation/inhibition balance may be a main cause of autism. Dr. Tang holds a position at the Simons Center for the Social Brain and holds research funds from the Rett Syndrome Research Trust.
