Vitamin-D deficiency (VDD) is associated with greater inflammation by up-regulation of inflammatory markers like, IL-6, TNF-α, activated monocyte phenotypes (CX3CR1+and CCR2+) in HIV-infected patients, which have been related to tissue dysfunction, comorbidity development, AIDS progression, and death in HIV-infected individuals [22]. The gene discussed is IL6; the disease is vitamin D deficiency.
