_Natural Molecules in Neuroprotection and Neurotoxicity_ brings together research in the area of natural compounds and their dual effects of neuroprotection and neurotoxicity when interacting with brain cells. This book is organized into four sections that address molecular mechanism underlying neuroprotection and neurotoxicity, neuroprotection mediated by natural molecules, neurotoxicity induced by natural compounds and nanotechnology-related strategies utilized in neuroprotection. Written by well-known researchers all over the world, chapters provide an in-depth analysis of numerous molecules, such as algae, plant and fungus-derived molecules, and comprehensively discuss their mechanisms of action and possible clinical applications. This book provides an essential reference for researchers and clinical scientists interested in the effects of natural compounds on the human health and disease. * Covers both neuroprotective and neurotoxic outcomes resulted from the exposure of brain cells to natural molecules * Analyzes numerous natural compounds, including animal, vegetal, fungal, bacterial, and marine-derived molecules * Discusses the effects of the metabolism of microbiota on the biotransformation of natural molecules and the consequences of these processes on brain cells * Contains a section focused on the nanotechnology-related strategies utilized to enhance the bioavailability of natural molecules to brain cells
