Our guts may not provide long-lasting systemic immunity from Covid-19, which is where immune cells circulate through the body to provide protection to other organs, finds a new study that may have implications for oral coronavirus vaccines.

A team of researchers from the University Hospital Erlangen, Germany, studied the role of the gut in providing systemic immunity to this virus.

An analysis of blood samples from patients infected with SARS-CoV-2 revealed that immune cells circulating in the blood, which were triggered by the gut’s response to infection, were limited in number when compared to immune cells that had been triggered elsewhere in the body.

“Although the gut is considered an important portal of entry for the virus, the immune response in the blood of Covid-19 patients is dominated by lymphocytes, cells that protect the body from infection, that have been triggered by other areas of the body,” said Sebastian Zundler, from the varsity’s Department of Medicine.

The team used a technique called flow cytometry to detect and measure the different types of immune cells that were found in the blood samples of patients currently with Covid-19, patients recovered from Covid-19, and those free of the virus.

There is a special mechanism in the lymphoid tissue of the gut that triggers the production of an imprint marker called “a4b7 integrin”. This marker causes T cells to head towards the gut to fight infection.

“We found relatively few immune cells with this marker in the blood of patients with Covid-19. This could be because of the “dilution” by cells generated at other sites of infection, most probably the lung, or alternatively by the selective attraction of these gut-imprinted immune cells to organs other than the gut since there was no difference between patients with and without symptoms that suggested an intestinal element to their infection,” explained lead author Tanja Muller, from the varsity.

The researchers speculate that if the gut-imprinted immune cells are diluted in comparison to immune cells triggered by other parts of the body, there could be implications for the oral-based Covid-19 vaccines currently under development. (IANS/KB)

Amitabh Bachchan, during his speech to the crowd of over 80,000 people at the Reliance Industries' annual event, said that the legacy left by Dhirubhai has had a positive impact on millions of people's lives worldwide.

A much moved Amitabh Bachchan, during his speech to the crowd of over 80,000 people at the Reliance Industries' annual event, said that the legacy left by Dhirubhai has had a positive impact on millions of people's lives worldwide.

When Bollywood superstar Amitabh Bachchan became bankrupt in the late 1990s, Dhirubhai Ambani stepped forward to give him financial assistance. In his speech, Bachchan remembered that Dhirubhai had sent Anil Ambani to offer him financial assistance during the crisis, which he had respectfully declined. Lenders began knocking on his door, losses mounted, and his bank account dwindled to nothing. He said, "Dhirubhai's money might have gotten me out of the problem quickly. However, I respectfully declined his offer and gradually began to find work again, which let me pay off my debt."

Irrespective of the age of your child, it is vital for parents to offer that extra support and assistance following an unsettling event.

In comparison to adults, children are prone to getting traumatized by troubling events easily, and this makes it important for parents to help their children when the times are tough. It could be a brutal accident, an unprecedented pandemic, a violent crime, or other disasters but with the right parental support, children have a higher chance of coming out stronger from an awful situation.

Anuja Kapur, Psychologist shares few tips wherein you can assist your child when tough times comes calling:

Every child responds differently to disturbing events:
What children feel about a current disaster in their life and how they react to it can come and go in waves. Children can act moody and withdrawn at times, struck with sorrow and fear at other times. There's no absolute "right" or "wrong" way to feel after a traumatic event so make sure not to dictate what your child or how your child should feel and react to the event.

European consumers will be able to use a single charger for all their portable electronics - an important step to increase convenience and reduce waste.

The European Commission, the executive arm of the European Union (EU), has announced plans for smartphone and other electronics manufacturers to fit a common USB-C charging port on their devices in an effort to reduce waste. In addition to phones, the rules will apply to other devices like tablets, headphones, portable speakers, videogame consoles, and cameras, reports The Verge. The decision will have a huge impact on Apple, as the company still uses its own Lightning connector to charge iPhones. The proposals only cover devices using wired, not wireless and a USB-C port is only mandatory for devices that charge using a cable.
