Описание: A. Definitions of Transformation in vitro When normal tissues or organs are explanted to conditions favoring the growth of cells as individual units ("cell culture"), the original cell population undergoes a large variety of modifications. Only a minority of the cells will thrive and multiply and within a rather short period of time, the complex composition of the original explant is replaced by a much simplified one of only a few recogniz- ably different cell types. With most organs fibroblast-like cells survive longest and outgrow other types. This is then a stable state of affairs for many gener- ations. This treatise will not discuss whether this simplification and stabilization represents selection of certain pre-existing cell types or a modification of cells into only a few recognizably different categories; for an excellent review see HARRIS. (1964). Table 1. Terminology Employed to Describe Transformations in vitro Type of transformation Essential features Irregular growth Lack of contact inhibition of cell membrane movement ("ruffled membranes") between juxtaposed cells Unrestrained growth Deficient inhibition of the cell cycle (mitosis) in a crowded culture Infinite growth Capacity of cells to undergo an infinite number of di- visions (formation of established cell lines) Cells may depart from this typical behavior in numerous ways involving for instance cellular morphology, immunology, chromosomes or metabolism. Such changes have, sometimes rather vaguely, been called "transformations". This is unprecise and the term "transformation" will here be used exclusively to indicate disturbances in cell growth related to neoplasia.

Описание: It is now widely acknowledged that at the beginning of this century Claude von Pirquet first pointed out that a viral disease, i. e., measles, resulted in an anergy or depression of preexisting immune response, namely, delayed continuous hypersensitivity to PPD derived from Mycobacterium tuberculosis. Thereafter ob- servations that viral infections may result in immunosuppression have been recorded by many clinicians and infectious disease investigators for six or seven decades. Nevertheless, despite sporadic reports that infectious diseases caused by viruses may result in either transient or prolonged immunodepression, investigation of this phenomenon languished until the mid-1960s, when it was pointed out that a number of experimental retroviral infections of mice with tumor viruses may result in marked immunosuppression. However, it was not until the recognition of the new epidemic of acquired immunodeficiency syn- drome (AIDS) caused by the human immunodeficiency virus and related vi- ruses that acquired immunodeficiencies associated with virus infection became general knowledge among biomedical investigators as well as the lay public. A number of reviews published during the past decade or so pointed out that numerous viruses may affect humoral and cellular immune responses. Furthermore, expanding knowledge about the nature and mechanisms of both humoral and cellular immunity and pathogenesis of viral infections has pro- vided clinical and experimental models for investigating in depth how and why viruses of man and animals profoundly affect immune responses.

Описание: This study aims to provide researchers with background information on the spread of AIDS and HIV among intravenous drug users as well as material on the clinical and psychological effects of HIV-1 infection and AIDS in Europe.
Описание: There have been tremendous advances in understanding the cellular mechanisms involved in sepsis and contributing to the development of multiple organ dysfunction and mortality in this setting. The chapters in this book provide up-to-date insights into important pathways that are initiated by sepsis.
