We previously demonstrated that human airway smooth muscle (ASM) cells express a functional IL-9R that mediate CCL11 expression.
Noteably, a mouse model of fungal keratitis in the cornea using mice that do not express a functional NOX complex showed that neutrophil NOX expression was required for inhibiting A. fumigatus growth [ 10].
The DN3 thymocyte subpopulation can be subdivided into cells that have not yet completed TCR-β locus rearrangements and those that express a functional TCR-β subunit that allows surface expression and signalling of the pre-TCR complex.
Indeed, RUNX1 expression was not significantly modified in proliferative HaCaT cells when ΔNp63 expression was decreased, conversely to what was observed in HPK that express a functional p53 protein (compare Figures 4d with 3b).
Previously, we showed that human ASM express a functional IL-9R and activation through this pathway lead to CCL11 expression.
Given our ability to express a functional TCR in Jurkat T cells, we next sought to validate expression in primary human CD4+ T cells.
One goal of gene transfer may be to express a functional gene when the endogenous gene is inactive.
These sensors are incorporated into cells or organisms as plasmid DNA, which leads the transcriptional and translational machinery of the cell to express a functional sensor.
C57BL/6J mouse bone marrow-derived macrophages (BMDMs) that express a functional NLRP1b allele (B6Nlrp1b+) can be induced to undergo caspase-1-dependent pyroptosis when stimulated with Bacillus anthracis lethal toxin (LeTx).
Despite mutation, the cells in this tumor population continued to express a functional immunoglobulin molecule and to retain, over a span of 3 years, the idiotypic determinant defined by the 4D6 monoclonal antibody.
Both cell lines were infected with WT PR8 or an NS1 mutant virus that does not express a functional form of the main viral factor suppressing cell antiviral responses (NS1-N81)45.To characterize viral infection, cells were fixed at 8 and 16 hpi, stained for NP protein and imaged by confocal microscopy (Fig. 8a).
