چکیده

Mycobacterium tuberculosis accelerates the progression of human immunodeficiency virus type 1 (HIV-1) infection. The results of this study, which show that thalidomide inhibits the upregulation of HIV-1 expression in U1 cells stimulated with mycobacterial lipoarabinomannans, support the rationale behind conducting controlled trials of this immunodeficiency agent with patients dually infected with HIV-1 and M. tuberculosis.

Thalidomide inhibits the replication of human immunodeficiency virus type 1.

Thalidomide, a selective inhibitor of tumor necrosis factor alpha (TNF-alpha) synthesis, suppresses the activation of latent human immunodeficiency virus type 1 (HIV-1) in a monocytoid (U1) line. The inhibition is dose dependent and occurs after exposure of the cells to recombinant TNF-alpha, phorbol myristate acetate, lipopolysaccharide, and other cytokine combinations. Associated with HIV-1 i...

Thalidomide suppresses Up-regulation of human immunodeficiency virus coreceptors CXCR4 and CCR5 on CD4+ T cells in humans.

Concurrent infection in patients with human immunodeficiency virus (HIV) infection increases the expression of HIV coreceptors CXCR4 and CCR5. Thalidomide has beneficial effects in a number of HIV-associated diseases. The effect of thalidomide on CXCR4 and CCR5 expression on CD4+ T cells was determined. Thalidomide produced a dose-dependent inhibition of lipopolysaccharide (LPS)-induced up-regu...

Thalidomide-induced antigen-specific immune stimulation in patients with human immunodeficiency virus type 1 and tuberculosis.

Thalidomide, which inhibits monocyte tumor necrosis factor (TNF)-alpha production and costimulates T cells, was tested for immune modulation in patients with human immunodeficiency virus (HIV) infection and tuberculosis (TB) in a placebo-controlled study. Thalidomide therapy resulted in increased levels of plasma interleukin (IL)-2 receptor, soluble CD8, interferon-gamma, and IL-12, indicating ...

Intestinal Pseudo-Obstruction as an Unusual Gastrointestinal Presentation in Pediatric Human Immunodeficiency Virus Infection

Intestinal pseudo-obstruction is a condition in which the intestine’s ability to push food through is reduced. It often leads to the dilation of the various parts of the bowel. It can be idiopathic or inherited from a parent, or caused by another disease. We report a rare case of human immunodeficiency virus (HIV) infection in a 3-year-old boy who referred with acute abdominal pain, and was lat...

Expression of human immunodeficiency virus coreceptors CXC chemokine receptor 4 and CC chemokine receptor 5 on monocytes is down-regulated during human endotoxemia.

Lipopolysaccharide (LPS) can inhibit human immunodeficiency virus (HIV) infection in monocytes in vitro. To test the hypothesis that an LPS effect on CXC chemokine receptor 4 (CXCR4) and CC chemokine receptor 5 (CCR5), known coreceptors for HIV, contributes to this effect, 8 healthy men were intravenously injected with Escherichia coli LPS (4 ng/kg), and monocyte CXCR4 and CCR5 expression was m...
