Biological membranes are often effected by diseases. Molecular events leading to or arising from pathological changes in the course of different diseases are as yet not clearly understood. This competent study by leading experts covers changes of the cellular environment, membranes and the metabolic functions during tissue growth and differentiation as well as aspects of abnormal organelle function in lysosomal storage diseases, peroxisomal and mitochondrial disorders, enzyme defects and regulatory defects of receptors due to oncogenes.Biological membranes are often effected by diseases.
