Compared to those without ARS, participants with ARS were in later Fiebig stages with higher HIV RNA in blood, colon, and cerebrospinal fluid; higher total HIV DNA in blood; CD4 depletion in blood and colon; and elevated plasma tumor necrosis factor alpha (TNF-α), C-reactive protein, and D-dimer (all P < .05).
Expression of tumor necrosis factor alpha (TNF alpha), interleukin 1 beta (IL-1 beta), and interleukin 6 (IL-6) was evaluated in unstimulated peripheral blood monocytes obtained from human immunodeficiency virus-positive (HIV+) individuals using a reverse transcription-polymerase chain reaction (RT-PCR) method.
Plasma levels of soluble CD14 and tumor necrosis factor-alpha type II receptor correlate with cognitive dysfunction during human immunodeficiency virus type 1 infection.
The results showed that pro-inflammatory cytokines: Tumour necrosis factor-alpha (TNF-α), Interleukin-6 (IL-6) and anti-inflammatory cytokines Interleukin-4 (IL-4), Interleukin-10 (IL-10) and Transforming growth factor-beta (TGF-β) were significantly elevated in HIV infected subjects before commencement of therapy compared to 6 months and 12 months into therapy (P < 0.01) and compared to control participants (P < 0.01).
Soluble TNF receptor type II (sTNF alpha RII) levels in serum, CD4 lymphocyte counts, and human immunodeficiency virus (HIV) burdens have each been correlated with HIV disease progression.
Elevated levels of tumor necrosis factor alpha (TNF-alpha) in human immunodeficiency virus type 1-transgenic mice: prevention of death by antibody to TNF-alpha.
There was a statistically significant positive association between the basal level of TNF-alpha production and the level of HIV gag transcripts of HIV-positive placental trophoblastic cells.
During RAAS activation, lipocalin 2 was related to biomarkers of inflammation (tumor necrosis factor α [P = .007]), monocyte/macrophage activation (soluble CD163 [P = .005] and chemokine [C-C motif] ligand 2 [P = .03]), and markers of cardiac stretch (brain natriuretic peptide [P < .001] and N-terminal fragment of the prohormone brain natriuretic peptide [P = .001]) in HIV.
Using cohorts of HIV-infected and HIV-uninfected individuals with latent Mtb infection (LTBI) and with active TB disease, we stimulated peripheral blood mononuclear cells (PBMC) for 6 hours with Mtb peptide pools and evaluated co-expression profiles of the inhibitory receptors BTLA, CTLA-4, and PD-1 on IFN-γ<sup>+</sup>/TNF-α<sup>+</sup> Mtb-specific CD4 T cells.
In prototypic models of chronicity--infection with human immunodeficiency virus (HIV) or lymphocytic choriomeningitis virus (LCMV)--we used transcriptome-based modeling to reveal that CD4(+) T cells were co-exposed not only to multiple inhibitory signals but also to tumor-necrosis factor (TNF).
This RaSH approach has previously documented high sensitivity and effectiveness in identifying genes that are differentially expressed as a function of induction of terminal differentiation in human melanoma cells, resistance or sensitivity to human immunodeficiency virus-1 (HIV-1) infection of human T cells and perturbation in gene expression in normal human fetal astrocytes infected with HIV-1 or treated with HIV-1 gp120 viral envelope glycoprotein or tumor necrosis factor-alpha (TNF-alpha).
Tumor necrosis factor-alpha induces circular forms of human immunodeficiency virus type-1 DNA in the persistently infected low-level expressing cell line, ACH-2.
Furthermore, we also described a correlation in the expression of CD300e and CD300f receptors with TNF-α production in response to LPS, only in monocytes of HIV-1-infected patients before vaccination.
In this study, we identify astrocyte elevated gene-1 (AEG-1), a human immunodeficiency virus 1 or tumor necrosis factor α-inducible oncogene, as a novel modulator of reactive astrogliosis.
ACH-2 cells, 200,000/ml, were treated with Cur-AgNP for 24-48 h. Expression of HIV-1 LTR and p24, the pro-inflammatory cytokines, IL-1β, TNF-α, and NF-κB was quantitated.
The effect of extracellular domain of human immunodeficiency virus (HIV-1) transmembrane glycoprotein gp41 on interleukin (IL)-10, IL-2, interferon (IFN)-y, IL-4, and tumor necrosis factor-alpha production by human peripheral blood mononuclear cells (PBMC) was assessed by ELISA.
Silencing with siBeclin1, but not siATG5, caused a significant decrease in HIV and morphine-induced interleukin (IL)-8 and tumor necrosis factor alpha (TNF-α) release, while secretion of IL-8 was significantly induced with rapamycin.
Persistent expansion, in a human immunodeficiency virus-infected person, of V beta-restricted CD4+CD8+ T lymphocytes that express cytotoxicity-associated molecules and are committed to produce interferon-gamma and tumor necrosis factor-alpha.
A higher stimulus-induced IL-10 secretion and a lower constitutive TNF-alpha mRNA were associated with a slower rate of disease progression, and TNF-alpha mRNA expression correlated with lower plasma HIV RNA.
