The dynamic properties of biological membranes

Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences
G K Radda


Biological membranes must be viewed as highly dynamic, undergoing continuous structural fluctuations and changes in response to external perturbations. The study of liposomes by 31 P n.m.r. and fluorescence can reveal some of the motional characteristics of the different regions in a bilayer. Asymmetric lipid distribution and how this depends on the environment is also observed by n.m.r. The nature of the interaction of amine anaesthetics and of polypeptide antibodies with membranes is discussed in relation to their perturbing effect. The role of lipid mobility in modulating hormone-receptor interaction is discussed with reference to the binding of thyroid stimulating hormone.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.
