Study shows COVID-19 vulnerability is highly dependent on host genetic architecture

A new US study available on the preprint server medRxiv reveals certain genetic variations that are associated with infection susceptibility and diverse clinical presentation of coronavirus disease (COVID-19) – including asymptomatic cases and severe forms of the disease in younger patients.

New discovery could end chronic rejection of transplanted organs

Chronic rejection of transplanted organs is the leading cause of transplant failure, and one that the field of organ transplantation has not overcome in almost six decades since the advent of immunosuppressive drugs enabled the field to flourish.

Repurposing existing drugs is a more rapid alternative than developing COVID-19 vaccine

Repurposing existing medicines focused on known drug targets is likely to offer a more rapid hope of tackling COVID-19 than developing and manufacturing a vaccine, argue an international team of scientists in the British Journal of Pharmacology today.

Pangolins may be the key to new COVID-19 treatments

Researchers at the Medical University of Vienna, Austria, have made an important discovery about the immune response to coronaviruses in pangolins that could point to new approaches for treating human cases of infection.

Predicting the dose for repurposing nitazoxanide in COVID-19

A new study published on the preprint server medRxiv in May 2020 reports a model that could help evolve appropriate dosage protocols for future clinical trials of the repurposed drug nitazoxanide in COVID-19 prevention and treatment. The researchers say, “It was possible to achieve plasma and lung tizoxanide concentrations, using proven safe doses of nitazoxanide, that exceed the EC90 for SARS-CoV-2.”

Vitamin D could improve outcomes in COVID-19

A new study published on the preprint server medRxiv* in May 2020 shows that vitamin D could have a beneficial effect on the course of illness for COVID-19 patients.

Modified dialysis device treats COVID-19

As part of a randomized controlled trial, a team from Lawson Health Research Institute is the first in the world to treat a patient with COVID-19 using a modified dialysis device.

New technique could revolutionize treatment for Alzheimer's, epilepsy, brain tumors

University of Virginia researchers are pioneering the use of focused ultrasound to defy the brain's protective barrier so that doctors could, at last, deliver many treatments directly into the brain to battle neurological diseases.

AI-enabled precision medicine may increase survival rate of patients with COVID-19-related sepsis

Data scientists from UK-headquartered AI precision medicine company, PrecisionLife, have used the Company’s proprietary AI enabled precision medicine platform to identify 59 repurposing drug candidates that could be used to develop new therapeutic strategies to increase the survival rate of patients who develop sepsis while suffering from severe COVID-19.

Study discovers inhibition of SARS-CoV-2 entry priming protein by approved drug

The COVID-19 pandemic caused by the severe acute respiratory syndrome -coronavirus 2 (SARS-CoV-2) has spread to most of the world, causing millions of cases and hundreds of thousands of deaths. A new study published on the preprint server bioRxiv* shows that a protease inhibitor drug already approved by the Food and Drug Administration (FDA) could inhibit viral entry.

Low CD8 and NK cell counts in the lung linked to high SARS-CoV-2 ACE2 receptor levels

A new study published on the preprint server bioRxiv in April 2020 reports that low levels of specific immune cells, namely, CD8 T cells and NK cells, are linked to higher expression of the ACE2 molecule, which acts as a receptor for the CoV.

Interleukin-12 electroporation led to clinical responses in patients with advanced melanoma

Combining intratumoral electroporation of interleukin-12 (IL-12) DNA (tavokinogene telseplasmid, or TAVO) with the immune checkpoint inhibitor pembrolizumab (Keytruda) led to clinical responses in patients with immunologically quiescent advanced melanoma, according to results from a phase II trial.

Cytokine storms created by COVID-19 could be reduced by using blood filter

Cytokine storms created by COVID-19 are causing major organ destruction and death, and for the first time in the United States, when patients begin to show signs of trouble, physicians are replacing the usual filter in a kidney dialysis machine with a filter known to trap these tiny proteins, with the goal of avoiding the devastation.

COVID-19 progression linked to B cell activation

The disease course of COVID-19 is diverse, ranging from asymptomatic to fatal respiratory failure. Scientists have been working to uncover the immunological reasons behind this heterogeneity. A recent study on B cells, published on the preprint server medRxiv in April 2020, shows that extrafollicular B cells could be a marker of severe infection in the early stages, predicting the need for earlier immunomodulatory therapy.

Researchers discover a new way to reduce implant rejection

The team from the University of Nottingham's Schools of Pharmacy and Life Sciences have found that the surface shape (topography) and chemical composition of polymer materials can be changed to create materials that control the body's immune response.
