Is prolyl hydroxylase domain enzyme 2 the major player in regulating hypoxic responses in rheumatoid arthritis?
Our data suggest that PHD-2 is the major hydroxylase regulating HIF levels and the expression of angiogenic genes in arthritic cells. PHD-2 appears to regulate responses relevant to arthritis via HIF-α, highlighting the major importance of this enzyme in hypoxia- and angiogenesis-dependent inflammatory diseases such as RA.
Helminths were found to be associated with an increased HIV RNA level. Successful treatment of intestinal helminths reduced plasma HIV RNA levels in chronic HIV-1 subtype C infection. Considering the high endemicity of helminths in tropical settings, the management of chronically HIV-infected individuals must include deworming.
