Teeth might preserve centuries-old antibodies: Study

Antibodies are proteins produced by the immune system as a natural response to infectious organisms like viruses and bacteria.

In a study by iScience, antibodies extracted from 800 year-old medieval human teeth were found to be stable and still able to recognise viral proteins.(Unsplash)

Air pollution’s link to Covid needs attention

Decision-makers cannot afford to be lulled into complacency by the lack of an active Covid-19 wave, or smoggy skies — the two crises have claimed lives

The authors of the study published in Environmental Health Perspectives believe the microscopic particles in bad air cripple the immune system’s response by inducing “oxidative stress” and causing inflammation, effectively decreasing the production of antibodies and other immune responses. (ANI)

Covid infection through womb caused brain damage in two infants: Study

Neither of the babies tested Covid positive at birth but developed high levels of antibodies in their blood against the virus.

Doctors earlier suggested possibilities of infection from pregnant mothers to their infant through placenta but there was no direct evidence until now. (Getty Images)

High air pollution hits Covid vaccine response: Study

The research team measured three kinds of antibodies (IgM, IgG and IgA) to five viral antigens (three of them on the spike protein contained in the vaccine).

Why antibodies aren't the only defense against Omicron

These Y-shaped proteins have made top news recently because Covid-19 shots don't produce as many of them that work against the heavily mutated Omicron variant compared to past strains -- at least, not without a booster.

Trained by both vaccines and infection, antibodies grab on to the spike protein that studs the surface of the coronavirus, stopping it from penetrating cells and sickening the host. (Representational Image)

Immune system has a backup plan for waning antibodies, says study

Researchers reveal there is a backup plan of the immune system, against waning of the antibodies over time, which does not rely on booster shots of Covid-19 vaccines

Blood clots in severe Covid cases linked to abnormal antibody response: Study

A latest study suggests that inflammation and blood clotting seen in very severe cases of COVID-19 may be caused by the antibodies sent to fight the disease triggering unnecessary platelet activity in the lungs.

Plasma therapy treatment yields mixed results in Uttarakhand hospitals

Convalescent plasma therapy involves extraction of plasma from the blood of Covid-19 patients four weeks after they have been cured of their viral infection. The extracted plasma is injected into Covid-19 patients. The antibody that develops in a recovered patient helps other Covid-19 patients to fight the virus.

Indian scientists grapple with antibodies issue, say it may not guarantee protection from COVID-19

Given that there are neutralising antibodies and also ‘simple’ antibodies, Indian scientists reveal that it may not be that useful to stop further spread of the coronavirus
