The extent of leukocyte adhesion and transmigration did not significantly differ between the groups undergoing microinjection of MIP-1α, PAF, and E. coli (Fig. 3A, B).
C. jejuni transmigration did not quantitatively correlate with the intracellular invasiveness of these isolates and a similar repertoire of strains including Inv+/Trans+, Inv+/Trans- and Inv-/Trans+ isolates were found as described above.
Transmigration did not perturb TCRζ expression because the proportions of TCRζbright and TCRζdim T cells were similar to those in PB cultured for the same period in the absence of endothelial cells or Transwell, nor was it dependent on proliferation because CFSE fluorescence of migrating and nonmigrating T cells was comparable (data not shown).
Wild-type (JR-CSF or NL4.3), but not envelope deficient HIV-1 (ΔE NL4.3), transmigrated through PGEC (Figure 5B, top panel), demonstrating that the PGEC layer does not allow nonspecific transmigration of viruses.
Such findings provide additional support that the control mechanisms for the different steps of trafficking are not directly linked, ie, the act of adherence does not automatically cause cellular transmigration.
The focus on optimization of cART to reach therapeutic concentrations in CNS addresses control of HIV replication in resident cells but does not address the important mechanism of continued transmigration during therapy.
Finally, he does not appear to completely reject the possibility of some kind of transmigration of souls, especially of miserable souls, in spite of the fact that he does not overtly affirm it and that many other passages seem to deny it (Schmidtke 1999).
These findings suggest that laminin α5 does not support T cell migration across the BBB basement membrane and may even redirect T cells to specific sites devoid of this laminin isoform, where α6β1-integrin/laminin α4 binding will facilitate the transmigration of T lymphocytes across the endothelial basement membrane into the perivascular space [ 85].
Although the initial results supported increased adherence under ethanol treatment, transmigration of PBMCs did not follow the same trend.
