The importance of showing up at the right place at the right time is instilled in leukocytes, just as it is in each one of us, by our parents. The fact that leukocyte infiltration of a newly established allograft typically presages the development of acute rejection is the downside of having an exquisitely tuned and finely balanced immune system. Chemokines binding to their receptors on leukocy...
background :the ccr5 is a chemokine receptor that serves as a co-receptor for hiv-1 attachment and entry to t lymphocytes. a 32bp deletion (∆32) in this gene is believed to be associated with resistance to infection and delay disease progression. the aim of this study was to determine the ∆32 allele frequency in healthy individuals and hiv-infected individuals with aids. methods : in this exp...
BACKGROUND Chemokine receptors have been suggested to be preferentially expressed on CD4+ T cells with CCR3 and CCR8 linked to the T helper (Th) 2 subset and CCR5 and CXCR3 to the Th1 subset, however this remains controversial. OBJECTIVE Our aim was to compare the CCR3, CCR5, CCR8 and CXCR3 expression in memory Th cells from allergic, asymptomatically sensitized and healthy individuals. MET...
Hemofiltrate C-C chemokine (HCC)-1 is a recently cloned C-C chemokine that is structurally similar to macrophage inflammatory protein (MIP)-1alpha. Unlike most chemokines, it is constitutively secreted by tissues and is present at high concentrations in normal human plasma. Also atypical for chemokines, HCC-1 is reported not to be chemotactic for leukocytes. In this paper, we have investigated ...
OBJECTIVE Leukocyte infiltration in ischemic areas is a hallmark of myocardial infarction, and overwhelming infiltration of innate immune cells has been shown to promote adverse remodeling and cardiac rupture. Recruitment of inflammatory cells in the ischemic heart depends highly on the family of CC-chemokines and their receptors. Here, we hypothesized that the chemokine decoy receptor D6, whic...
Recent evidence suggests that the chemokine axis of CXC chemokine ligand-12 and its receptor CXC chemokine receptor-4 (CXCL12/CXCR4) is highly expressed in gynecological tumors and the axis of CXC chemokine ligand-16 and CXC chemokine receptor-6 (CXCL16/CXCR6) is overexpressed in inflammation-associated tumors. This study aimed to determine the relationship between CXCL12/CXCR4, CXCL16/CXCR6 an...
The unexpected encounter, 10 years ago, between human immunodeficiency virus (HIV) and the chemokine system has dramatically advanced our understanding of the pathogenesis of AIDS, opening new perspectives for the development of effective prophylactic and therapeutic measures. To initiate infection, the HIV-1 external envelope glycoprotein, gp120, sequentially interacts with two cellular recept...
