Abstract

IgE antibody production to exoenzymes and common antigen (OEP) of P. aeruginosa was studied in mice that were injected with the antigens incorporated into water-in-oil-in-water (w/o/w) emulsion or Al(OH)3 gel. OEP and protease toxoid (PT) elicited IgE antibody response but elastase toxoid (ET) did not. Capacity of the OEP to produce IgE antibody was reduced remarkably by it's protease treatment, which suggested that the capacity lies in the protein portion of OEP. The w/o/w emulsion was less effective than Al(OH)3 gel in adjuvanticity to elicit IgE antibody response, but the emulsion enhanced the IgM and/or IgG antibody response to PT and maintained a constant level for a long period. These findings may suggest that IgE antibody response to some components of P. aeruginosa could be induced in man. High serum level of IgE was observed in some cases of cystic fibrosis caused by P. aeruginosa infection, although the IgE antibody activity has not yet been 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.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.
