Receptor uptake arrays for vitamin B12, siderophores and glycans shape bacterial communities

, 2017
Molecular variants of vitamin B12, siderophores and glycans occur. To take up variant forms, bacteria may express an array of receptors. The gut microbe Bacteroides thetaiotaomicron has three different receptors to take up variants of vitamin B12 and 88 ...

Gephyrin Regulates the Cell Surface Dynamics of Synaptic GABAA Receptors

Journal of Neuroscience, 2005
The efficacy of fast synaptic inhibition is critically dependent on the accumulation of GABAA receptors at inhibitory synapses, a process that remains poorly understood.

Effects of acute exercise on expressions of functional receptors on CD56dim and CD56bright natural killer cells [PDF]

, 2014
PURPOSE: Mobilization and cytotoxicity of natural killer (NK) cells are regulated by cell surface receptors such as adhesion molecules and activating/inhibitory receptors.

Heterodimerization of μ- and δ-Opioid Receptors Occurs at the Cell Surface Only and Requires Receptor-G Protein Interactions*

Journal of Biological Chemistry, 2005
Homo- and heterodimerization of the opioid receptors with functional consequences were reported previously. However, the exact nature of these putative dimers has not been identified. In current studies, the nature of the heterodimers was investigated by

Increased accuracy of ligand sensing by receptor internalization

, 2010
Many types of cells can sense external ligand concentrations with cell-surface receptors at extremely high accuracy. Interestingly, ligand-bound receptors are often internalized, a process also known as receptor-mediated endocytosis.

Cell surface protein receptors in oral streptococci [PDF]

FEMS Microbiology Letters, 1994
Streptococci have a vast repertoire of adherence properties which include binding to human tissue components, epithelial cells and to other bacterial cells. These interactions are determined by the expression of cell-surface receptors some of which are species-specific.

Cell Receptors for Influenza A Viruses and the Innate Immune Response

Frontiers in Microbiology, 2012
The interaction of the hemagglutinin (HA) of the influenza A viruses (IAV) with the cell surface is a key factor for entry of the virus and productive infection of the cell.

Direction of actin flow dictates integrin LFA-1 orientation during leukocyte migration

Nature Communications, 2017
Integrin αβ heterodimer cell surface receptors mediate adhesive interactions that provide traction for cell migration. Here the authors show that actin flow can orient cell surface integrins during leukocyte migration, suggesting integrin activation by ...

Cell-surface receptors in health and disease.

Clinical Chemistry, 1979
Abstract Assessment of interaction of hormones and neurotransmitters with their cell-surface receptors can lead to an understanding of the molecular mechanisms that underlie diseases in man involving resistance and supersensitivity to these humoral agents and to pharmacological agents.
