An Introduction to Receptors and Receptor Disorders
Experimental Biology and Medicine, 1979 SummaryIn the last decade reliable methods have been introduced to quantitate and characterize receptors for hormones and other biologically interesting ligands. Applied initially to hormone receptors on malignant cells and to androgen-resistant and insulin-resistant states, these methods have led to the identification of many disease processes where ...

, 2021 The renin-angiotensin-aldosterone system (RAS) is a vital hormone-receptor system that regulates cardiovascular and renal functions. In this article, we discuss exciting new findings in the RAS field. Recently solved active state crystal structures of Angiotensin II type 1 (AT1R) and type 2 receptor (AT2R) helped in understanding receptor activation ...

Adenosine A1 receptor: Functional receptor-receptor interactions in the brain [PDF]
Purinergic Signalling, 2007 Over the past decade, many lines of investigation have shown that receptor-mediated signaling exhibits greater diversity than previously appreciated. Signal diversity arises from numerous factors, which include the formation of receptor dimers and interplay between different receptors.

Cold Spring Harbor Perspectives in Biology, 2010 Of the established Ca2+-mobilizing messengers, NAADP is arguably the most tantalizing. It is the most potent, often efficacious at low nanomolar concentrations, and its receptors undergo dramatic desensitization. Recent studies have identified a new class of calcium-release channel, the two-pore channels (TPCs), as the likely targets for NAADP ...

The Journal of Pediatrics, 1981 Cells are endowed with specific cognitive molecules that function as receptors for hormones, neurotransmitters, and other intercellular messengers. The receptor molecules may be present in the plasma membrane, cytoplasm, or nucleus. When occupied by the messenger, the receptor is coupled to the cellular machinery that responds to the message-bearing ...

The Scientific World JOURNAL, 2007 Lipoxins (LXs) represent a class of arachidonic acid (AA) metabolites that carry potent immunoregulatory and anti-inflammatory properties, LXA4and LXB4being the main components of this series. LXs are generated by cooperation between 5-lipoxygenase (LO) and 12- or 15-LO during cell-cell interactions or by single cell types. LX epimers at carbon 15, the

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy
Policy Studies Journal, EarlyView.ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.
