Biochem/physiol Actions

DAPTA is a potent CCR5 antagonist, an amidated octapeptide corresponding to an HIV envelope glycoprotein gp120 (gp160)-derived sequence (aa 185-192; the SF-2 isolate) that competes against gp120-CD4 complex for interaction with CCR5 (IC50 = 0.42 nM against gp120CM235 binding to CCR5/CD4 cells, IC50 = 1.5/1.8 nM against gp120BaL/sCD4 or gp120CM235/sCD4 binding to CCR5+/CD4- cells). DAPTA blocks CCR5-dependent HIV host cell entry in cultures and in vivo.

The octapeptide Ala-Ser-Thr-Thr-Thr-Asn-Tyr-Thr (peptide T) and two structural analogs are potent agonists of human monocyte chemotaxis, evincing identical rank potency orders as was previously shown for their inhibition of human immunodeficiency virus (HIV) envelope binding and T cell infectivity. Chemotactic

As recently described, the administration of extremely low doses (pg/kg) of CCL4 (Macrophage inflammatory protein 1β, MIP-1β) can induce antinociceptive effects in mice (García-Domínguez et al., 2019b). We describe here that hydrodynamic delivery of a plasmid containing CCL4 cDNA provokes

Background: Cigarette smoke exposure (CSE) is a major cause of chronic obstructive pulmonary disease (COPD). The smoke disrupts cell-cell adhesion by inducing epithelial barrier damage to the tight junction (TJ) proteins. Even though the inflammatory mechanism of chemokine (C-C motif)
