Indian-American physician identifies attainable COVID-19 remedy


WASHINGTON: An Indian-American scientist has found a possible technique to stop life-threatening irritation, lung harm and organ failure in sufferers identified with COVID-19.

Printed on-line within the journal Cell, the analysis coming from the lab of Dr Thirumala-Devi Kanneganti, an Indian-born researcher working at St. Jude Kids’s Analysis Hospital in Tennessee, recognized the medicine after discovering that the hyperinflammatory immune response related to COVID-19 results in tissue harm and multi-organ failure in mice by triggering inflammatory cell dying pathways.

The researchers detailed how the inflammatory cell dying signaling pathway labored, which led to potential therapies to disrupt the method.

“Understanding the pathways and mechanism driving this irritation is essential to develop efficient remedy methods,” mentioned Kanneganti, vice chair of the St Jude Division of Immunology.

Kanneganti was born and raised in Telangana.

She acquired her undergraduate diploma at Kakatiya College in Warangal, the place she majored in Chemistry, Zoology, and Botany.

She then acquired her M.Sc. and Ph.D from Osmania College in India.

She joined St.Jude, in Memphis, Tennessee, USA, in 2007.

“This analysis gives that understanding. We additionally recognized the particular cytokines that activate inflammatory cell dying pathways and have appreciable potential for remedy of COVID-19 and different extremely deadly illnesses, together with sepsis,” she mentioned.


The opposite researchers have been Shraddha Tuladhar, Parimal Samir, Min Zheng, Balamurugan Sundaram, Balaji Banoth, R Ok Subbarao Malireddi, Patrick Schreiner, Geoffrey Neale, Peter Vogel and Richard Webby, of St. Jude; and Evan Peter Williams, Lillian Zalduondo and Colleen Beth Jonsson, of the College of Tennessee Well being Science Heart.

COVID-19 is brought on by the SARS-CoV-2 virus.

The an infection has killed greater than 1.2 million folks in lower than one yr and sickened hundreds of thousands extra. The an infection is marked by elevated blood ranges of a number of cytokines.

These small proteins are secreted primarily by immune cells to make sure a fast response to limit the virus.

Some cytokines additionally set off irritation.

The phrase cytokine storm has been used to explain the dramatically elevated cytokine ranges within the blood and different immune modifications which have additionally been noticed in COVID-19, sepsis and inflammatory issues equivalent to hemophagocytic lymphohistiocytosis (HLH), St Jude’s mentioned in a press release.

However the particular pathways that provoke the cytokine storm and the next irritation, lung harm and organ failure in COVID-19 and the opposite issues have been unclear.

The mobile and molecular mechanisms that comprehensively outline cytokine storm was additionally missing.

Kanneganti’s crew centered on a choose set of probably the most elevated cytokines in COVID-19 sufferers.

The scientists confirmed that no single cytokine induced cell dying in innate immune cells, it mentioned.

“The findings hyperlink inflammatory cell dying induced by TNF-alpha and IFN-gamma to COVID-19,” Kanneganti mentioned.

“The outcomes additionally recommend that therapies that concentrate on this cytokine mixture are candidates for fast scientific trials for remedy of not solely COVID-19, however a number of different usually deadly issues related to cytokine storm,” she mentioned.

“We have been excited to attach these dots to know how TNF-alpha and IFN-gamma set off PANoptosis,” mentioned co-first writer Rajendra Karki, a scientist within the Kanneganti laboratory.

“Certainly, understanding how PANoptosis contributes to illness and mortality is essential for figuring out therapies,” added co-first writer Bhesh Raj Sharma, a scientist within the Kanneganti laboratory.
