Identification of a region in p47phox/NCF1 crucial for phagocytic NADPH oxidase (NOX2) activation.

abstract：:HIV infection results in depletion and dysfunction of naïve CD4(+) T cells. The mechanisms underlying these deficiencies are not understood. We investigated the frequencies of CD4(+) naïve subsets in HIV disease as defined by expression of CD25 and/or FoxP3 and the relationship of these frequencies to naïve T cell pro...
