Covid: How Delta, Kappa Variants Evade Immune System
Covid: How Delta, Kappa Variants Evade Immune System

The Delta Plus variant caused the greatest decrease. Antibodies from half of the Janssen-vaccinated individuals completely lost the ability to neutralise one or more variants in the laboratory assay.

Vitamin D may protect severe Covid infection, death: Study

An international study found that a good amount of Vitamin D in the body before Covid-19 infection can prevent severe disease and death.

Covid Vaccine
Response Of Covid Vaccine Low For Some People With Weak Immune System: Study

Among some people with weak immune systems, the response of two doses of Covid vaccine remains low or absent, according to a study.

COVID Alters Fight-Or-Flight Response In Healthy Young People
COVID Alters Fight-Or-Flight Response In Healthy Young People

The team conducted a series of tests to show that young adults recovering from SARS-CoV-2 have elevated resting sympathetic activity, but similar heart rate and blood pressure, compared with control subjects.

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.

Abnormalities In T Cells Of Immune System Linked To Severe COVID-19
Abnormalities In T Cells Of Immune System Linked To Severe COVID-19

Tokyo: Researchers have found that abnormalities in the immune system’s T cells is linked to pneumonia seen in COVID-19 patients. Further, the researchers have claimed that the findings may lead to new ways of avoiding severe lung infection caused by the novel coronavirus. According to the study, published in the journal Frontiers in Immunology, critically […]

Seriously Ill Covid-19 Patients' Antibodies Affect Immune System

London: Researchers have found that people seriously ill with the Covid-19 disease have antibodies that are blocking so-called interferons, which are an important part of the body´s immune mechanism. While most people dying from Covid-19 are elderly, up to five to 10 per cent of younger adults and children can also be seriously infected by […]

Teachers' Day: TV Actors Share Important Life Lessons Learnt From Covid-19 Pandemic
Mild Covid-19 Cases May Trigger Lasting Immunity

London: Mild cases of Covid-19 can trigger robust memory T cell responses — an essential part of the immune system, even in the absence of detectable virus-specific antibody responses, say researchers. The study, published in the journal Cell, revealed that memory T cell responses generated by natural exposure to or infection with SARS-CoV-2, the virus […]

Healthy Diet
COVID-19: Dietary Supplements Important Weapon For Fighting Off Coronavirus

New York: Diet supplements containing vitamins C and D and other micronutrients are a safe, effective, and low-cost means of helping your immune system fight off COVID-19 and other acute respiratory tract diseases, say researchers. According to the study, published in the journal Nutrients, public health officials should issue a clear set of nutritional recommendations […]

Liquor Consumption Increases Risk Of COVID-19 Infection

Hyderabad: On the eve of the World Liver Day, being observed amid the coronavirus pandemic, medical experts have warned that excessive liquor consumption weakens the immune system, making one more vulnerable to infections like COVID-19. A substance called ethanol or ethyl alcohol present in alcoholic beverages harms the immune system of an individual. Other toxic […]

Eating Too Much Salt In Diet Weakens Immune System

London: Do you add more salt to your diet than others? Did you know eating too much salty diet can weaken your immune system! Researchers have found that too much salt in your diet will weaken your immune system and it will be challenging for your body to fight off bacterial infections under such circumstances. […]

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 […]

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 […]

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 […]

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 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 […]
