SARS-CoV-2 can infect blood monocytes and trigger inflammation, finds study

Researchers found about 10% of blood monocytes in coronavirus disease 2019 (COVID-19) patients are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These monocytes then die, leading to the release of cytokines – a feature associated with severe and critical COVID-19.

Study clarifies the role of collagen during pancreatic cancer development

Contrary to long-held beliefs, Type I collagen produced by cancer-associated fibroblasts may not promote cancer development but instead plays a protective role in controlling pancreatic cancer progression, reports a new study from researchers at The University of Texas MD Anderson Cancer Center.

SARS-CoV-2 modulates host cell central carbon metabolism for reproduction

A team of scientists from Sweden and India has recently characterized the host cell metabolic alterations associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Their findings reveal that SARS-CoV-2 modulates the host cell's central carbon metabolism to facilitate replication and infection propagation.

SARS-CoV-2 does not infect the entire body in the same way, finds study

COVID-19, the disease caused by the pandemic coronavirus SARS-CoV-2, is primarily regarded as a respiratory infection. Yet the virus has also become known for affecting other parts of the body in ways not as well understood, sometimes with longer-term consequences, such as heart arrhythmia, fatigue and "brain fog."

Study identifies immune profile of people with severe COVID-19

A team of researchers at Georgetown University Medical Center, USA, investigated how SARS-CoV-2 affects the immune system’s response during and after infection and contributes to the severity of COVID-19.

COVID-19 and lung cancer have a common pathway, say researchers

A new preprint on the bioRxiv* server describes the common features COVID-19 shares with lung cancer.

Researchers study host and viral transcriptomes in tandem to shed light on SARS-CoV-2 infection

In a new study, researchers discuss the use of simultaneous sequencing of both human and viral genes to better understand SARS-CoV-2's infection pathway.

Study describes mechanism that limits immunosupressive activity of tumor-associated macrophages

Tumor cells are able to avoid the attack of the immune system through several mechanisms. For instance, these can secrete factors that turn macrophages -cells in the immune system- into dual action agents that contribute to the tumor progress and will protect it from immune body defenses: these become, thus, the tumor-associated macrophages (TAMs).

Could Galectin-3 be a potential biomarker to help identify severe COVID-19 early?

Researchers have measured the galectin-3 levels in the sera of hospitalized patients. They found initial high levels indicate patients will become severely ill, suggesting it could be used as a predictor of severe disease.

Can early use of colchicine reduce COVID-19 mortality?

The COVID-19 pandemic, caused by SARS-CoV-2, has caused well over 2.3 million deaths in a little over a year. A new meta-analysis reports the potential utility of colchicine in treating SARS-CoV-2 infection and forestalling severe and life-threatening inflammation of the lungs and other organs.

Insight into role of aging in response to SARS-CoV-2 infection

Researchers at the University of California, Irvine set out to determine the differences between young people and older adults regarding their host responses against SARS-CoV-2. The team revealed that independent of disease severity, COVID-19 was linked to a significant shift in plasma inflammatory factors. The research is posted to the pre-print server medRxiv*.

Elevated ACE2 and inflammation levels increase risk for pregnant women infected with SARS-CoV-2

Among the hundred million or so cases of coronavirus disease 2019 (COVID-19) that have occurred since the pandemic began, pregnant women have been a conspicuous risk group. However, the exact nature of the risk they and their fetuses face, and the mechanism by which it operates, is far from clear.

SARS-CoV-2 triggers development of new-onset IgG autoantibodies in hospitalized COVID-19 patients

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent for coronavirus disease 2019 (COVID-19), is associated with several clinical features common in autoimmune diseases as myalgias, arthralgias, fatigue, and rashes. COVID-19 patients also exhibit less common autoimmunity manifestations such as myositis, thrombosis, myocarditis, encephalitis, vasculitis, and arthritis.

Colchicine may have therapeutic potential against COVID-19

A new study describes the results of colchicine in mitigating the inflammatory storm associated with COVID-19, and thus preventing a percentage of severe and critical cases.

Study unravels relationship status of important receptor on immune and cancer cells

An important receptor on the surface of cancer and immune cells prefers to remain noncommittal; sometimes it is present as a single, sometimes as a pair. This was first shown by an MDC team in the journal PNAS, and will decisively advance the development of new medications.

ACE2 and furin levels linked to inflammation in smokers with COVID-19

A new study reports the level of ACE2 and furin, two enzymes that are intimately linked to infection with SARS-CoV-2, the causative agent of COVID-19.

NK and T cell subsets show distinctive lung-homing receptor profiles in COVID-19 patients

A new study reveals in detail the changes that occur in peripheral blood natural killer (NK) and T cells in COVID-19.

SARS-CoV-2 viral load in saliva may be linked to COVID-19 disease severity

Researchers at Yale University School of Medicine found that SARS-CoV-2 viral loads in saliva are higher for patients with associated risk factors and underlying conditions that lead to severe COVID-19 and death. Thus, saliva viral loads could be used to predict disease severity.

Immune-inflammatory mediators indicate that rejection and tissue injury can be avoided with drugs

Immune inflammatory mediators are critical in pathology, transplantation, and regenerative medicine, scientists report in The American Journal of Pathology

SARS-CoV-2 surface proteins alter the expression of key chemokines and cytokines in cell lines

Researchers from the Washington University School of Medicine, United States of America, recently demonstrated that the SARS-CoV-2 surface proteins alone triggered innate cell activity and the interferon signaling pathway.
