Ludwig Cancer Research study profiles immune landscape of brain tumors

A Ludwig Cancer Research study has profiled, in a sweeping comparative analysis, the distinct immune landscapes of tumors that arise in the brain, or gliomas, and those that metastasize to the organ from the lungs, breast and skin.

Inhibiting tumor signals can suppress the spread of cancer

For most people who die of cancer, the spread of the initial tumor is to blame. "Metastasis is what kills most cancer patients," says Serge Fuchs, a professor in Penn's School of Veterinary Medicine.

New strategy identified to address the underlying cause of LAD1 patients' symptoms

Owing to a rare genetic mutation, individuals with leukocyte adhesion deficiency type 1 (LAD1) experience a suite of symptoms that trace back to an immune system dysfunction.

IL-6 blocker use in severe COVID-19 increases risk of secondary infections

With many hundreds of thousands of deaths due to the current COVID-19 pandemic, there is a rush to find an effective vaccine or drug against the virus. A new study on the preprint server medRxiv* in May 2020 shows that the use of some biologically plausible drugs may be counterproductive, and care should be taken when trying out unproven therapies.

Understanding why pancreatic ductal adenocarcinoma is so aggressive

Pancreatic ductal adenocarcinoma (PDA) is a deadly cancer, killing patients within a year. CSHL Professor Christopher Vakoc and his former postdoc Timothy Somerville discovered how pancreatic cells lose their identity, acquire a deadly new identity, and recruit nearby cells to help them grow, promote inflammation, and invade nearby tissues.

The use of rheumatoid arthritis drug sarilumab in severe COVID-19 pneumonia

A new study published on the preprint server medRxiv* in May 2020 reports the beneficial effects of the monoclonal antibody sarilumab in severe COVID-19 pneumonia.

Kawasaki disease outbreak in children with COVID-19

The ongoing COVID-19 pandemic has marched its way to almost all parts of the world, with hundreds of thousands of deaths and over 4.5 million cases as of May 15, 2020. One saving grace has been the apparent sparing of children, though the mortality in older people is quite high.

Experts review symptoms, diagnosis, and current treatment of COVID-19

The ongoing economic and social impact of the pandemic is staggering, but despite a daily flood of news on the disease, few laypeople know that paradoxically, COVID-19 mostly kills through an overreaction of the immune system, whose function is precisely to fight infections.

Research examines molecules derived from ticks as potential COVID-19 treatment option

UK-based biotechnology firm ILC Therapeutics is working alongside the University of Oxford to examine the use of Evasins – molecules derived from ticks – as a potential COVID-19 treatment option for patients whose lungs are badly damaged by the virus and face a critical juncture in recovery.

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.

Mapping complex peripheral immune response to severe COVID-19

In a recent article publicly available at medRxiv, researchers from Stanford have presented a single-cell atlas of the peripheral immune response to coronavirus disease (COVID-19), highlighting pertinent immunological features associated with the severe forms of the disease.

Higher blood levels of NETs linked to more severe COVID-19 infection

New research finds a connection between destructive white blood cells and a more severe disease course in patients with COVID-19.

Study creates a new platform to study single-cell genomics of many diseases

Although advances in genetics and genomics reveal numerous disease-associated gene mutations, physicians and researchers still wrestle with the tricky challenge of linking those mutations to actual disease-causing processes.

Are overactive immune cells causing COVID-19-related deaths?

While the COVID-19 pandemic is devastating many regions, the world over, a new paper published in the Journal of Experimental Medicine in April 2020 describes the possibility that the critical or very severe cases of COVID-19 are due to the production of neutrophil extracellular traps (NET) due to hyperactivated immune cells.

China with the world: COVID-19 experts dialogues - the 4th talk transcript

Q (Prof. Singer): What do you think about the comorbidities and the age of the patients in the treatment of COVID-19? Is the mortality higher in elderly patients as it is reported from recent papers?

Molecular pathway responsible for TNBC's progression and spread identified

Immunotherapies have revolutionized treatment for people with a variety of cancers. But when given to those with triple-negative breast cancer, a particularly aggressive form of the disease, less than 20% respond.

Bacteria-trapping protein may contribute to breast cancer metastasis

The protein peptidyl arginine deiminase 4 (PAD4), which enables some immune cells to trap bacteria, promoted breast cancer metastasis in mice when expressed in cancer cells, according to data published in Molecular Cancer Research, a journal of the American Association for Cancer Research.

New bacteria-killing light-activated coating

A new antimicrobial coating that can be activated by light has been reported by researchers in the journal Nature Communications, in March 2020. The coating can be used to prevent transmission from computer and phone screens and keyboards, the inside of catheters, and breathing tubes. All these are significant routes of healthcare-associated infections (HCAIs).

New sepsis intervention enhances the body's bacteria-capturing neutrophil extracellular traps

Researchers at Children's Hospital of Philadelphia have developed a novel treatment for sepsis - one of the leading causes of hospital death - that enhances the body's bacteria-capturing neutrophil extracellular traps so that they more effectively capture infectious bacteria, resist degradation, and improve sepsis outcomes and survival.
