Macrophage heterogeneity

Vox Sanguinis
K E HopperD S Nelson

Abstract

Macrophages are a mobile, functionally diverse group of cells which may be recruited and stimulated to a high degree of metabolic activity. Heterogeneity may be detected from one site to another and result from local influences, e.g. lung v. peritoneal cells, or occur within a population and arise dur to different stages of differentiation, maturation or activation or possibly from distinct cell lines. Recruitment and turnover are important determinants of the diversity of cells at any one site. In addition, anti-tumour, anti-microbial and secretory capacities of macrophages are greatly influenced by the degree and nature of stimulation possibly affecting only a subpopulation of the cells. Accessory cell activity is also a function of a minor population of macrophages which have distinct surface antigens. The sources of the heterogeneity and the interrelationship between the macrophages subpopulations remain to be determined.

COVID-19

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.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.

Super-resolution Microscopy

Super-resolution microscopy is the term commonly given to fluorescence microscopy techniques with resolutions that are not limited by the diffraction of light. Here are the latest discoveries pertaining to super-resolution microscopy.
