Evidence for multiple cell surface chicken fetal-leukemic antigens (CFA) in the developing chick and other avian species

Abstract

Chicken fetal antigen (CFA), a membrane antigen present on fetal chicken red blood cells is lost with chicken development, and reappears on the red blood cells of leukemic chickens. Seven avian species were found to possess CFA. A species hierarchy comparing the quantitative expression of CFA has been established. The levels of CFA expression with development are compared in the chicken and Japanese quail. Specific adsorptions of R-anti-CFA with avian red blood cells revealed the existence of multiple CFAs. Four groups of antigenic determinants (CFA a,b,c,d) have been characterized and defined by their expression among avian species. Multiple CFA determinants are discussed with regard to possible membrane alterations and gene function.

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.

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.

Autism: Motor Learning

A common feature of autism spectrum disorder (ASD) is the impairment of motor control and learning, consistent with perturbation in cerebellar function. Find the latest research on ASD and motor learning here.

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.

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

Protein Localization in Disease & Therapy

Localization of proteins is critical for ensuring the correct location for physiological functioning. If an error occurs, diseases such as cardiovascular, neurodegenerative disorders and cancers can present. Therapies are being explored to target this mislocalization. Here is the latest research on protein localization in disease and therapy.

Genetic Screens in Bacteria

Genetic screens can provide important information on gene function as well as the molecular events that underlie a biological process or pathway. Here is the latest research on genetic screens in bacteria.
