Most gut intraepithelial cells (IEL) of the mouse are T cells that bear CD8 molecules, present either as alpha-beta chain heterodimers (CD8 beta+) or as alpha chain homodimers (CD8 beta-). All CD8 beta+ IEL bear alpha/beta T cell receptors (TCR); CD8 beta- IEL bear either alpha/beta or gamma/delta TCR and are considered to be a thymus-independent (TI) population, probably arising locally from a...

The characterization of a scintillating metal organic framework (MOF) is not straightforward, mainly due to the small size and low density material. In this context, we present herein generic method give an easy access determination key parameter in scintillation field, namely light output. To reach this, MOF-205 was first synthesized as millimetric-size single crystals then sintered under pres...

Functionally active gamma interferon (IFN-gamma) receptors consist of an alpha subunit required for ligand binding and signal transduction and a beta subunit required primarily for signaling. Although the receptor alpha chain has been well characterized, little is known about the specific role of the receptor beta chain in IFN-gamma signaling. Expression of the wild-type human IFN-gamma recepto...

The dynamics of interacting dark matter-dark energy models is characterized through an interaction rate function quantifying the flow between these sectors. In most functions, expansion Hubble considered and sometimes it argued that, as a local property, inclusion may influence overall dynamics. This starting point present article where we consider very simple cosmic scenario vacuum cold matter...

GABA is the main inhibitory neurotransmitter in the mammalian brain. The postsynaptic GABAA receptor/pore complex is presumed to be a pentamer typically composed of a combination of alpha, beta, and gamma subunits, although the stoichiometry remains controversial. We probed the stoichiometry of the GABAA receptor by site-directed mutagenesis of a conserved leucine (to serine) in the putative se...

PURPOSE Previous studies have shown that alpha-crystallin, a major lens protein, acts as a chaperone preventing the thermal denaturation of other lens crystallins. However, there has not been an examination of the alpha-crystallin chaperone ability with respect to the types of insult thought to cause human cataract. Therefore, an examination of the chaperone potential of alpha-crystallin under ...

Like the gamma-subunit of Na-K-ATPase, the corticosteroid hormone-induced factor (CHIF) is a member of the FXYD family of one-transmembrane-segment proteins. Both CHIF and two splice variants of gamma, gamma(a) and gamma(b), are expressed in the kidney. Immunolocalization experiments demonstrate mutually exclusive expression of CHIF and gamma in different nephron segments. Specific coimmunoprec...

Forskolin treatment of cells expressing Torpedo acetylcholine receptors leads to enhanced assembly efficiency of subunits, which correlates with increased phosphorylation of the gamma subunit. To determine the role of the two potential protein kinase A sites of the gamma subunit in receptor assembly, cell lines expressing different mutant receptors were established. Mouse fibroblast cell lines ...

The human liver alpha alpha alcohol dehydrogenase exhibits a different substrate specificity and stereospecificity for secondary alcohols than the human beta 1 beta 1, and gamma 1 gamma 1 or horse liver alcohol dehydrogenases. All of the enzymes efficiently oxidize primary alcohols, but alpha alpha oxidizes secondary alcohols far more efficiently than human beta 1 beta 1 and gamma 1 gamma 1 or ...
