Antibodies Improve In Quality For Months After Covid Vaccination: Study
Antibodies Improve In Quality For Months After Covid Vaccination: Study

The researchers found that B cells targeted against SARS-CoV-2 persisted in the germinal centres - like boot camps where B cells are trained to make ever-better-quality antibodies - of all participants for months. Even six months after vaccination, 10 out of 15 people still had B cells in their germinal centres.

Know How Immune System May Help Prevent Miscarriage

A subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the foetus, the placenta and other tissues involved in pregnancy.

Gene linked to hair loss may improve cancer treatment

New York: Scientists have found that a gene associated with autoimmune hair loss disorder may also help improve cancer immunotherapy — treatment that uses body’s own immune system to fight cancer. The findings showed that a gene named IKZF1 recruits T cells in alopecia areata — a condition in which immune cells attack and destroy […]

Mosquito
Mosquito saliva can affect immune system for a week

New York: Components in the mosquito saliva can trigger an unexpected and long-lasting immune responses — up to seven days post-bite, say scientists. The researchers found that more than 100 proteins in mosquito saliva are mediating the effects on the immune system, or may help the virus become more infectious. Identifying these proteins could help […]

Baking soda may help combat rheumatoid arthritis

New York: Drinking baking soda daily may help reduce the destructive inflammation of autoimmune diseases like rheumatoid arthritis, say scientists. While the immune system normally protects us from disease and infection, in someone who has an autoimmune disease the immune system attacks healthy cells in the body by mistake. Drinking baking soda, or sodium bicarbonate, […]

Decoded: How HIV evades immune system

London: Scientists have discovered how HIV virus avoids elimination from the immune system, a finding which could pave the way for the cure for over 40 million people infected worldwide. Currently, HIV can be treated with anti-retroviral therapy, which merely prevents its progression to AIDS, but does not offer the cure. The researchers found that […]

Toxic nanoparticles from tattoo ink can travel inside body

London: If you are planning to ink a tattoo, think twice. According to a study, the components in the tattoo ink transports various pigments and toxic element impurities inside the body in micro and nano-particle forms to the immune system, which could have an unknown effect on the body. When a tattoo is etched on […]

Antibody that can help kill cancer cells emerges

New York: Researchers have found that an antibody — originally developed for studying the autoimmune condition multiple sclerosis — can promote the immune system’s ability to fight cancer and decreases tumour growth. In a study published in the journal Science Immunology, the researchers reported that the antibody decreased tumour growth in models of melanoma (skin […]

Low humidity raises flu risks during winter season

New York: Low humidity is a key reason behind people falling sick and even dying from flu during the winter months, says a study. Decreased humidity lowers the immune system’s defences against flu infection, says a study published in the journal Proceedings of the National Academy of Sciences (PNAS). It offers an insight into why […]

Loneliness May Increase Inflammation In Body

London: Researchers have found that social isolation and loneliness could be associated with increased inflammation in the body, though loneliness and isolation should neither be used interchangeably nor grouped together. For arriving at the findings, published in the journal Neuroscience & Biobehavioural Reviews, researchers analysed 30 previous studies to investigate the link between social isolation […]

Preterm babies can acquire their immune system

London: Babies who born prematurely can rapidly acquire some adult immune functions after birth, equivalent to that achieved by infants born at term, according to a new study. For the findings, published in the journal Nature Communications, the research team followed babies born before 32 weeks gestation to identify different immune cell populations, the state […]
