A rapid way to track an elusive part of the immune system will bring better vaccine strategies — ScienceDaily

Bozz District

Researchers from Duke-NUS Medical School, together with collaborators from the National Centre for Infectious Diseases (NCID) and Singapore General Hospital (SGH), have discovered a simple and rapid method to measure the T-cell immune response to the SARS-CoV-2 virus, which causes COVID-19.

A growing body of data now demonstrates the importance of both T cells and antibodies in the coordinated immune response against SARS-CoV-2. This method is a further boost to scientists who seek to routinely monitor and assess SARS-CoV-2-specific T-cell responses in vaccinated or convalescent individuals, as well as to test and verify the effectiveness of vaccines.

Immune cell betrayal explains why it gets colder as we age

Bozz District

Human evolution has provided us a level of protection from the existential threat of cold temperature with the capacity to produce heat from fat stored in the body. However, with age, people become more susceptible to cold as well as inflammation and metabolic problems which can lead to a host of chronic diseases. Researchers at Yale and the University of California-San Francisco (UCSF) have found one culprit in this process — the same immune cells within fat that are designed to protect us from cold temperatures.

In a new study, they find that the fat tissue of older mice loses

Britons with severely weak immune systems to be offered third Covid jab | Coronavirus

Bozz District

Half a million people with severely weakened immune systems are to be offered third Covid vaccine shots in a move that will increase debate over the rollout of booster jabs for the wider population.

The NHS will provide third doses for those aged 12 and up who have severely compromised or suppressed immune systems at a time decided by their clinicians. It follows a recommendation on Wednesday from the government’s Joint Committee on Vaccination and Immunisation (JCVI).

Health officials said the shots were not boosters, which are given to prolong people’s protection, but instead form part of the primary vaccination

Does Practicing Gratitude Help Your Immune System?

Bozz District

Being grateful seems to have a lot of positive effects on our lives. In fact, grateful people may have better sleep, healthier hearts, and fewer aches and pains.

But what is going on in our bodies when we’re grateful, that might help us be healthier? A couple of recent studies aimed to find out.

In the first study, 61 healthy women between the ages of 35 and 50 were randomly assigned to either a six-week online gratitude activity or a writing activity (as a comparison). Once a week, the gratitude group were given a writing prompt that asked them
