Interleukin-1 receptor antagonist (IL-1ra), tumor necrosis factor soluble receptors (sTNF-R) type I and II, and regulated upon activation, normal T-cell expressed and secreted (RANTES) play an important role in the modulation of primary glomerulonephritis (GN) course. The aim of the study was to assess whether pre-treatment measurements of IL-1ra, sTNF-R, and RANTES assessed conjointly may be u...

PURPOSE Synthesis of regulated on activation, normal T-cells expressed and secreted (RANTES) in the airway has previously been shown to be elevated after respiratory syncytial virus (RSV) infection. However, since few studies have examined whether RSV-infected asthma patients express a higher level of RANTES than do normal individuals, we used a murine model of asthma to address this question. ...

In the continued absence of an effective anti-HIV vaccine, approximately 2 million new HIV infections occur every year, with over 95% of these in developing countries. Calls have been made for the development of anti-HIV drugs that can be formulated for topical use to prevent HIV transmission during sexual intercourse. Because these drugs are principally destined for use in low-resource regions...

Trophoblast migration within the endometrium and uterine vasculature is essential for normal placental and fetal development. We previously demonstrated that macaque trophoblasts express the chemokine receptor CCR5 and that this receptor mediates trophoblast migration toward RANTES (regulated upon activation normal T-cell expressed and secreted). In the present paper we have used primary cultur...

We evaluated the presence and number of eosinophils at varying stages in the human corpus luteum from 27 ovaries of women at reproductive age. Eosinophils preferentially accumulated in dilated microvessels of the thecal layer transforming into septa of the corpus luteum. The granulosa layer under luteinization, the thecal layer, and haemorrhages in the former antrum each contained low, moderate...

BACKGROUND The mechanisms leading to hepatic injury in chronic hepatitis C virus (HCV) infection are only incompletely understood. Recent data propose a correlation of the intrahepatic expression of the CC chemokine RANTES and the degree of periportal and portal inflammatory liver damage. AIM Here, we have studied the intrahepatic mRNA levels of CC chemokines RANTES together with that of othe...

There is a relationship between CD4-T-cell number and circulating interleukin 7 (IL-7) levels in human immunodeficiency virus (HIV)-positive individuals. Here, we show that IL-7 induced a dose-dependent production of CCL3 (MIP-1alpha), CCL4 (MIP-1beta), and CCL5 (RANTES) in peripheral blood mononuclear cells (PBMC), ex vivo tonsil lymphoid tissue of HIV(-) individuals, and PBMC from HIV(+) indi...

Severe malarial anemia (MA) is the primary manifestation of severe malaria among children in areas of holoendemic Plasmodium falciparum transmission. Although overproduction of inflammatory-derived cytokines are implicated in the immunopathogenesis of severe MA, chemokines such as regulated on activation, normal T-cell expressed and secreted (RANTES, CCL5) are largely unexplored in childhood ma...

We have used total chemical synthesis to perform high-resolution dissection of the pharmacophore of a potent anti-HIV protein, the aminooxypentane oxime of [glyoxylyl1]RANTES(2-68), known as AOP-RANTES, of which we designed and made 37 analogs. All involved incorporation of one or more rationally chosen nonnatural noncoded structures, for which we found a clear comparative advantage over coded ...

Viral resistance to small molecule allosteric inhibitors of CCR5 is well documented, and involves either selection of preexisting CXCR4-using HIV-1 variants or envelope sequence evolution to use inhibitor-bound CCR5 for entry. Resistance to macromolecular CCR5 inhibitors has been more difficult to demonstrate, although selection of CXCR4-using variants might be expected. We have compared the in...
