Fas triggers apoptosis, or programmed cell death, in response to a variety of cell insults.
Fertilization triggers a rotation of the cortex relative to the cytoplasm that is associated with the movement of dorsal determinants from the vegetal pole to the future dorsal region of the embryo (Gerhart et al.
Cellulose acetate phthalate (CAP) is a promising microbicide candidate for prevention of infection by sexually transmitted disease (STD) pathogens, including HIV-1 [ 1 2 3 4 5 6 7 ] . CAP inactivates HIV-1 and blocks the coreceptor binding site on the virus envelope glycoprotein gp120, while leaving the site for the primary cellular receptor CD4 accessible [ 8 9 ] Soluble CD4 (sCD4) was shown to inhibit HIV-1 infection by two mechanisms: reversible blockage of virus binding to receptors, and irreversible inactivation of virus infectivity [ 10 ] . Since CAP and sCD4 bind to distinct domains on the HIV-1 envelope, it was of interest to determine whether or not these two ligands affect virus infectivity synergistically as do other combinations of anti-HIV-1 drugs and sCD4 [ 11 12 ] Binding of sCD4 leads to conformational changes in gp120 [ 13 14 15 16 17 ] . Binding of gp120 to coreceptors CXCR4 and CCR5, respectively, triggers additional conformational changes in HIV-1 envelope glycoproteins [ 18 19 ] For these reasons it was of interest to determine whether a) pretreatment of HIV-1 with sCD4 would affect subsequent binding of CAP to virus particles, and b) CAP binding to virus particles in the presence or absence of sCD4 would elicit conformational changes which could affect HIV-1 infectivity.
The simple answer is that we do not know exactly how exposure to antigen triggers either an immune reaction or tolerance.
The recE gene product of the Rac prophage converts dsDNA ends into 3' protruding single-stranded form and the recT gene product promotes recombination by annealing them with a homologous DNA in its vicinity (for review, see [ 7 8 ] ). This recombination may result in one progeny DNA (non-conservative recombination) or two progeny DNAs (conservative double-strand break repair) [ 9 ] . In a recBC sbcBC background, a ds end stimulates homologous recombination that results in only one progeny DNA (non-conservative recombination) [ 10 ] . Analysis of the stimulation of recombination by replication (for review, see [ 11 ] ) and analysis of altered chromosomal replication (for review, see [ 12 ] ) led to the proposal that a chromosomal ds break formed during replication fork arrest triggers homologous recombination, which would reconstitute a replication fork (for review, see [ 5 ] ).
