FIGURE 1.25 The virus life cycle. Viruses are mobile bits of genetic iuformatiou encapsulated in a protein coat. The genetic material can be either DNA or RNA. Once this genetic material gains entry to its host cell, it takes over the host machinery for macromolecular synthesis and subverts it to the synthesis of viral-specific nucleic acids and proteins. These virus components are then assembled into mature virus particles that are released from the cell. Often, this parasitic cycle of virus infection leads to cell death and disease.

A cell subjected to a stress of any kind can potentially exhibit a wide range of responses. Severe stress may lead to cell death and, ultimately, to cell lysis imposition of less severe conditions may result in a metabolically perturbed system, which may either revert to its initial state or adapt in some way to the imposed conditions. Figure 10 shows a hypothetical scheme, presented by Prokop and Bajpai [12], for the signal-response cascade associated with hydrodynamic shear stress. The signal reception/transduction mechanisms are, as yet, poorly understood. While Fig. 10 can be applied to any biological system, Namdev and... 

One type of test measures the inhibition of respiration of bacterial cells on pieces of pig skin by the substance under test. Here, the factor of correlation between cell death and cessation of respiration should be borne in mind.

Signals from neighbouring cells or tissues will instruct a particular cell to proliferate, differentiate into another cell type or to commit suicide by programmed cell death. Figure 10.4 shows that NFKB can play a major role in countering programmed cell death and hence survival of the cell after stimulation of the TNFa pathway. Such a pathway depends upon the activation of NFKB which will activate a variety of anti-apoptopic genes. 

Extended biological investigations concerning structure-function studies were further initiated to evaluate the abilities of these clusters to inhibit Con A-induced membrane type-1-matrix metalloproteinase (MTl-MMP)-mediated pro-MMP-2 activation, cell death, and antiproliferative property in mesenchymal stromal cells (MSC).83...

Thus, it is possible that recurrent mood disorders, as in the case of bipolar disorder, may lower the threshold for cell death and/or atrophy in response to a variety of other physiological (e.g. normal aging) and pathological (e.g. ischemic) events, and thereby contribute to a variety of deleterious health-related effects.
