Cellular Mechanism of Oxygen Sensing

Annual Review of Physiology, 2001
▪ Abstract  O2sensing is a fundamental biological process necessary for adaptation of living organisms to variable habitats and physiological situations. Cellular responses to hypoxia can be acute or chronic. Acute responses rely mainly on O2-regulated ion channels, which mediate adaptive changes in cell excitability, contractility, and secretory ...

Tactile Sensing Mechanisms

The International Journal of Robotics Research, 1990
This paper has three main themes: design of a cylindrical tactile sensor, mechanical analysis using planar linear elas ticity models, and signal analysis for determining basic infor mation about the applied contact. An analysis of appropriate sensor depth has been used to allow accurate localization of contacts and reduced spatial aliasing.

Intracellular Mechanisms of Oxygen Sensing

Biochemistry (Moscow), 2020
The review describes molecular mechanisms for sensing oxygen levels in various compartments of animal cell. Several pathways for intracellular oxygen sensing are discussed together with details of functioning of the near-membrane and cytoplasmic pools of molecular components in hypoxic cells.

Mechanisms of Membrane Curvature Sensing

Annual Review of Biochemistry, 2011
Bacteria and eukaryotic cells contain geometry-sensing tools in their cytosol: protein motifs or domains that recognize the curvature, concave or convex, deep or shallow, of lipid membranes. These sensors contrast with classical lipid-binding domains by their extended structure and, sometimes, counterintuitive chemistry.

Sense Organ Mechanisms

1991
Sense organs, or sensory receptors, form the interface between the animal’s environment on the one hand and its nervous system on the other. This interface is with both the internal and external environments and it is the function of the sense organs to monitor these environments.

Sense Organs: Mechanical and Chemical Senses

1972
THE SIMPLEST mechanical sense is that of touch. This may be subserved by (i) receptors of contact projecting from the surface of the body, (ii) sense organs stimulated by the strains set up in the cuticle by pressure, or (iii) organs sensitive to changes of tension within the body.

Glucose-sensing mechanisms in eukaryotic cells

Trends in Biochemical Sciences, 2001
Glucose not only serves as a nutrient but also exerts many hormone-like regulatory effects in a wide variety of eukaryotic cell types. Recently, interest in identifying general mechanisms and principles used to sense the presence of glucose has significantly increased and promising advances have been made: in yeast, the first proteins with an ...

Environmental Sensing Mechanisms in Bordetella

2001
The success of a bacterial pathogen may depend on its ability to sense and respond to different environments. This is particularly true of those pathogens whose survival depends on adaptation to different niches both within and outside the host. Members of the genus Bordetella cause infections in humans, other animals and birds.
