Immunological Reviews, 1998
Summary: Like other cells, T cells are dependent on signals from their environment for their survival. Resting T cells are supported in vitro by cytokines such as interleukin (IL)‐4, IL‐6 and IL‐7. The latter two cytokines are made constitutively in animals and hence might affect the lifetimes of their resting T cells.

The relation between the NSD concept and cell survival in fractionated irradiation is established; the slope of Strandquist's lines is related to the shape of survival curves for the given type of cells and radiation. A new parameter, CBE, derived from TDF for determining cumulative biological effect is proposed.

Recent polemics concerned with the problem whether the oxygen effect is pertinent or irrelevant to clinical radiotherapy (Hall 1967; Alper 1968) raised, among others, the question: For how long a period do cells actually survive under the severely anoxic conditions which may prevail at some sites in a tumour?

Critical Reviews in Oncology/Hematology, 2000
In contrast to most traditional cell culture systems, spheroids represent a unique opportunity to recapitulate aspects of cell homeostasis and as such better reflect in vivo tumor biology. This review highlights recent spheroid-based studies which have defined a role for intercellular adhesion in dictating cellular fate.

Plasma cell differentiation and survival
Current Opinion in Immunology, 2008Humoral immunity depends on the regulated production and maintenance of antibody secreting cells during the course of an immune response. Recent insights into the transcriptional regulation of the initiation of plasma cell differentiation have clarified aspects of this process, particularly with respect to the choice between the memory B cell and ...

Recent findings suggest that lymphocyte survival is a continuous active process and support the role of B cell receptor engagement in B cell survival. In this context the conflict of survival interests between the diverse B cells gives rise to a pattern of interactions which mimics the behavior of complex ecological systems.

Lokajiceek et al. (1979) have recently proposed an equation relating cell survival to TDF. Since TDF is additive, their equation (3) is The fraction of cells surviving after a course of irradiation is taken as or However, their conclusion that where α is a constant, is only true for the special case where the proportion of cell recovery between ...
