Drugs targeting neutrophils could reduce ARDS in severe COVID-19

Scientists in Taiwan recently published a report on their use of anti-neutrophil strategies to treat acute respiratory distress syndrome (ARDS) – a life-threatening condition that can arise in critical COVID-19 cases – in the journal Frontiers in Pediatrics.

Uracil point mutations found in SARS-CoV-2 variants alter innate immune responses

Tohoku University scientists have found that human editing enzymes are likely behind a type of mutation in the COVID-19 virus that stimulates the release of pro-inflammatory molecules called cytokines by immune cells in the body.

Exosome-mediated mRNA delivery generates broad immune response to multiple SARS-CoV-2 proteins

Recently, researchers from The Johns Hopkins University School of Medicine, Baltimore, MD, USA, and Capricor Therapeutics, Inc., Beverly Hills, CA, USA, described a new approach to SARS-CoV-2 vaccine development using exosomes to deliver mRNAs that encode the antigens from multiple structural proteins of the virus.

Delirium common after hospital discharge in critically ill COVID-19 patients

Anesthesiologist and other researchers from Michigan Medicine, Ann Arbor, New York Medical College, Valhalla and Center for Consciousness Science, University of Michigan Medical School, Ann Arbor, have reported a case series of critically ill coronavirus disease 2019 (COVID-19) patients who have developed neuropsychological symptoms after having been discharged from the hospital.

TB screening needed for people on methotrexate who live in at-risk areas

New research presented at ACR Convergence, the American College of Rheumatology's annual meeting, shows that tuberculosis (TB) screening and ongoing clinical care is needed for people on methotrexate who live in areas where the highly infectious illness is common.

DNase coated melanin-like nanospheres for sepsis treatment in severe COVID

As the treatment of severe COVID-19 is very difficult, the researchers from the Korea Research Institute of Biosciences and Biotechnology (KRIBB) suggested that DNase-1 can be utilized to dissolve the neutrophil extracellular traps (NETs), hence halting the further progression of COVID-19.

NIH awards $1.6 million for research on hormonal control of HIV latency

The National Institutes of Health has awarded $1.6 million to researchers at the George Washington University School of Medicine and Health Sciences for research on hormonal control of HIV latency.

The connection between severe COVID-19 and white blood cell counts

However, in other research, white blood cells' exact roles and subtypes in severe COVID-19 are still unclear. The team writes, "It is unknown if blood cell counts before infection are associated with the risk of developing severe COVID-19." They explained that the numbers of these cell types could be influenced by several factors such as age, gender, disease status, and medications.

Temple researchers identify criteria to predict cytokine storm in COVID-19 patients

Like a cold front that moves in, setting the stage for severe weather, coronavirus infection triggers showers of infection-fighting immune molecules - showers that sometimes escalate into a chaotic immune response known as a cytokine storm.

Higher levels of lymphocytes reduce risk of long-term complications in asymptomatic COVID-19 patients

COVID-19 remains stubbornly inconsistent. More than a million people have died and 35 million have been diagnosed, but a large fraction of people infected with the coronavirus--about 45%, according to recent estimates--show no symptoms at all.

Understanding the production of memory B cells and immune responses

The current COVID-19 climate has made vaccines, antibodies, and immune responses topics of everyday conversation.

Study shows how mutations in VAV1 gene may promote T-cell tumors in experimental mice

Life is an exquisite orchestration of growth and change, with checks and balances that fine-tune complex entwined interactions, both intrinsic and external.

Low lymphocyte count before COVID-19 heightens death risk

Researchers at the University of Rochester Medical Center have conducted a study suggesting that having a low white blood cell count (lymphocytopenia) prior to exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be associated with an increased risk of dying from coronavirus disease 2019 (COVID-19).

Another study finds cross-reactivity T cell responses against SARS-CoV-2

Using ELISpot and proliferation assays, researchers show strong responses in SARS-CoV-2 infected patients, but not so much in negative samples. However, there may be cross-reactive T cell responses from other human coronaviruses.

Study shows tofacitinib drug can repair permeability defects in the intestine

A team of researchers led by biomedical scientist Declan F. McCole at the University of California, Riverside, has found that the drug tofacitinib, also called Xeljanz and approved by the FDA to treat rheumatoid arthritis and ulcerative colitis, can repair permeability defects in the intestine.

Cincinnati Children's research leads to approval of new drug for hypereosinophilic syndrome

Following two decades of research on a group of rare diseases called hypereosinophilic syndrome at Cincinnati Children's Hospital Medical Center, the U.S. Food and Drug Administration has approved the drug Nucala (mepolizumab) for use in the treatment of patients with hypereosinophilic syndrome.

Targeted therapy found to be effective at shrinking tumors in patients with nonsmall-cell lung cancer

An international team of researchers has found that selpercatinib, a drug that precisely targets cancers driven by mutations or alterations in the gene RET, was effective at shrinking tumours in patients with nonsmall cell lung cancer (NSCLC), with a majority of patients living for more than a year without disease progression.

Risk factors for mortality among hospitalized patients with COVID-19

A new study by scientists at biotechnology company Genentech, Inc., and published on the preprint server medRxiv in September 2020 attempts to identify the factors which may shape the risk for death in COVID-19 disease.

27 Sep 2020

FDA approves first drug for patients with hypereosinophilic syndrome in nearly 14 years

Today, the U.S. Food and Drug Administration approved Nucala (mepolizumab) for adults and children aged 12 years and older with hypereosinophilic syndrome (HES) for six months or longer without another identifiable non-blood related cause of the disease.

Sticky DNA webs may cause tissue damage associated with severe COVID-19 infections

Sticky webs of DNA released from immune cells known as neutrophils may cause much of the tissue damage associated with severe COVID-19 infections, according to two new studies published September 14 in the Journal of Experimental Medicine.
