This book is a compilation of the most relevant molecular mechanisms and cellular processes that are involved in the infection processes in relation to lipid metabolism. The authors are international experts in the field of infection biology. Readers will understand infection metabolism and the contribution of lipids and lipid-protein interaction to lipids.Microbial lipids play an important role in almost all cellular phenomena. Microbial infections also contain an important virulence component in microbial lipids. The secretion of lipid vesicles that contain virulence factors, the assembly of lipid membrane microdomains harboring signal transduction pathways relate to infection process and the number of lipid-protein interactions that are necessary for the internalization of pathogens to host cells are some examples of the importance of lipids and lipid metabolism in the development of infections.
