Natural COVID-19 Infection Produces Robust T Cell Response and Memory to Fight Future Infections, Finds Study

By HospiMedica International staff writers Posted on 08 Sep 2020 Researchers from the University of Oxford (Oxford, UK) have found that natural infection with COVID-19 produces a robust T cell response, including inducing T cell ‘memory’ to potentially fight future infections. While research has shown that COVID-19 induces a B cell antibody response, it has been less clear whether COVID-19 causes the immune system to make virus-specific T cells too, and whether they are important for recovery from the initial infection, and protection against new infections. While antibodies latch onto and destroy disease-causing agents like viruses and bacteria, T cells latch on to diseased cells within the body, such as tumor cells or virus-infected cells. T-cells also help attract other immune cells to the area. T cells are attracted to tumor or viral protein fragments (called epitopes) displayed on the surface of diseased cells, which act like waving a flag ...

Oversensitive COVID-19 Tests Detecting Dead Coronavirus Cells, Driving False Positives and Reinfections

A study by the Oxford University’s Centre for Evidence-Based Medicine (Oxford, England) suggests that the current COVID-19 diagnostic tests could be too sensitive and may be detecting dead coronavirus cells, leading to overestimated infections. According to the researchers, the tests used to diagnose COVID-19 are so sensitive that they may be indicating people are infected with SARS-CoV-2 even when they had the virus 70 days ago. Prof Carl Heneghan, director of the Centre for Evidence-Based Medicine, believes that eight days after contracting COVID-19, the chances of an infected person passing on the virus to others become zero if there are no symptoms. However, fragments of the coronavirus can still remain in the body for several weeks afterwards. Polymerase chain reaction (PCR) tests currently used to detect SARS-CoV-2 have technical limitations as they cannot distinguish whether the virus in the patient is alive or dead. The researchers analyzed 25 studies on ...

What ingredients are in vaccines?

Vaccines are a central player in our fight against infectious diseases. What components are commonly found in vaccines, and what is their purpose? In this Special Feature article, we find out. Why do some vaccines have a long list of components? Many people will be familiar with the concept that a vaccine against a particular virus will contain a small amount of the pathogen or a part of it, at least. When we receive the vaccine, the viral interloper triggers our immune system to launch a series of events that leave us protected against the pathogen in the future. But a glance at the ingredients in common vaccines reveals a long list of other components, the roles of which might not seem so clear cut. What is the purpose of the likes of gelatin, thimerosal, and Polysorbate 80? And why do some vaccines contain aluminum? In this Special Feature article, ...

Can the keto diet help beat the flu?

Source: https://www.medicalnewstoday.com/articles/327186.php Results of a new study in mice suggest that the body may be able to defeat the influenza virus if a person has the right sort of diet — a ketogenic, or keto, diet. Infection with the influenza virus, better known as the flu, has accounted for 12,000–61,000Trusted Source deaths every year since 2010 in the United States, with an annual economic burden of $87.1 billionTrusted Source. The introduction of the flu vaccine has greatly improved infection and morbidity rates. However, there is still currently no cure for the illness. Healthcare professionals and scientists alike are continuing the search for novel therapeutics to combat the flu, yet the key may lie within the body’s own immune system. Moreover, it may be activated by the keto diet. Following the keto diet involves eating foods that are high in fat and low in carbohydrates. Meals tend to consist of ...

Metabolic Changes in Aging Cells

Aging is caused by the deterioration of various cellular organelles and physiological processes. The pathways elements that are affected during ageing include insulin resistance, changes in body composition, decline in growth hormone, insulin-like growth factor, and sex steroids.
