Specific, tight-binding protein partners are valuable helpers to facilitate membrane protein (MP) crystallization, because they can i) stabilize the protein, ii) reduce its conformational heterogeneity, and iii) increase the polar surface from which well-ordered crystals can grow. The design and production of a new family of synthetic scaffolds (dubbed(More)
The recognition of the monocyte/macrophage-activating properties of IL-2 has broadened our image of the biological effects of this lymphokine from those of a T cell growth factor to those of a molecule with pleiotropic effects. The detailed analysis of the mechanisms of action of IL-2 including its biological effects on different cell types and the(More)
Interleukin-8 (IL-8) is a neutrophil chemotactic and activating cytokine that is produced in response to several stimuli. Because monocytic cells are important producers of IL-8, we investigated whether interferon-gamma (IFN-gamma), a potent inducer of activation and differentiation of mononuclear phagocytes, affected IL-8 expression in this cell lineage.(More)
We studied the constitutive and lipopolysaccharide (LPS)-induced expression of nuclear protein binding to the negative regulatory element (NRE) of the human immunodeficiency virus type 1 (HIV-1) long terminal repeat (LTR) in fresh human monocytes. We demonstrated the existence of a constitutive factor binding to the NRE 73-bp HpaII/HpaII fragment (-216 to(More)
Chronic administration of dihydroergotoxine, at the two doses of 2.5 mg/kg and 5 mg/kg decreases the binding of dopamine 3H-agonists to striatal membranes. By contrast the binding of dopamine 3H-antagonists is decreased in the animals treated with the higher dose and increased in those treated with the lower one. In old rats, in which a partial loss of both(More)
