Abstract
Apoptosis is now recognised as the mechanism by which unwanted cells are tidily eliminated with no messy consequences such as inflammation. This is nowhere more important than in the immune system which is typified by the overproduction of all sorts of cells-particularly self-reactive lymphocytes-which would be a severe embarrassment to the organism if not removed. Autoimmunity and cancer are the consequences of not having enough apoptosis. Apoptotic mechanisms also play a role in killing of target cells by immune effector cells, as for example cytotoxic T cells. A volume dealing with apoptosis and immunity is therefore opportune. This book is a compilation of invited papers by eminent authors who have written ably on the nature of apoptosis in immunology. More accurately, apoptosis in lymphocytes as there is in fact little about the many interesting non-lymphocytic cells of the immune system, or other related haematopoietic cells. There is, in addition, some chapters on apoptosis in AIDS and so we see that this book is somewhat of a pot pourri of topics, all interesting, but neither providing nor presumably aiming to provide a comprehensive coverage. I do not see, for example, substantial sections on apoptosis in cytotoxic cell killing nor is material gathered together on apoptosis induced via the Fas/tumour necrosis factor receptor mediated pathways, although there are many scattered references to these. The value of such a book as this is rather that you might hope to find some interesting information that would otherwise have eluded you, and in this I for one was not disappointed. For example, I found there is evidence for proteases and the ubiquitin pathway in apoptosis, and I learned that p53 is not necessary for apoptosis induced by antiCD4 in peripheral T cells.
