Chemokine News and Research

RSS

Chemokines are a family of small cytokines, or proteins secreted by cells. Proteins are classified as chemokines according to shared structural characteristics such as small size (they are all approximately 8-10 kilodaltons in size), and the presence of four cysteine residues in conserved locations that are key to forming their 3-dimensional shape.

The impact of mild SARS-CoV-2 infection on maternal-fetal immunity

Recently, a new study published on the pre-print server bioRxiv* examined the effect that maternal asymptomatic COVID-19 had on decidual and peripheral immune cells during the later stage of pregnancy.

The influence of COVID-19 on platelet activation and aggregation

In a paper recently uploaded to the bioRxiv* preprint server, humanized ACE2 mice are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and platelets are subsequently isolated from the blood for quantitative proteomic analysis.

Researchers identify genetic markers linked to COVID-19 severity and susceptibility

In collaboration with Northwestern Medicine investigators, an international multi-center study has identified genetic factors associated with SARS-CoV-2 infection and COVID-19 severity, according to findings published in Nature.

Experimental drug combination extends survival in mice with lung cancer, study finds

A combination of experimental drugs increased the attack of immune cells on non-small cell lung cancer (NSCLC) to extend survival in mice, a new study found.

Research identifies key role of CXCL9 cytokine in age-related chronic inflammation

An inflammatory-aging clock called developed by Stanford University School of Medicine and the Buck Institute for Research on Aging can predict how strong your immune system will be in 10 years, when you'll become frail or whether you may develop cardiovascular diseases a few years down the road.

Stimulating immune cells to form special structures can potentiate pancreatic cancer chemotherapy

A new study from Queen Mary University of London has demonstrated that immune cells can be stimulated to assemble into special structures within pancreatic cancer such that, at least in a pre-clinical model, researchers can demonstrate an improvement in the efficacy of chemotherapy.

Gene variant in African Americans contributes to unnecessary bone marrow biopsies

A gene variant that lowers white blood cell levels and is common in individuals with African ancestry contributes to unnecessary bone marrow biopsies, according to a study published June 28 in JAMA Internal Medicine.

Study shows activation of CD16+ T-cells contribute to severe COVID-19 illness

Do T-cells play a protective immune role, or are they responsible for severe COVID-19 illness?

Could a fungus-derived compound reduce hyperinflammation in severe COVID-19?

New research from scientists at the University of Pennsylvania, USA, demonstrates that cyclosporine A (CSA), a calcineurin inhibitor that modulates cytokine production, may have potential antiviral properties against coronaviruses.

Which vitamins and minerals help with COVID?

A study published in the journal Inflammopharmacology reviewed recent data related to the role of vitamins and minerals in treating COVID-19 patients. The primary goal of the review is to highlight the possible therapeutic role of vitamins A, B, C, D, E and K, and micronutrients as immunity boosters in COVID-19 patients.

The role of natural killer cells in fight against viral infections including SARS-CoV-2

In an effort to further understand the role of NK cells in combatting COVID-19, a group of researchers explored NK cells in acute viral infections, citing flavivirus and influenza virus infections as examples.

Scientists decipher the activation mechanism of a chemokine receptor

Chemokine receptors, located at the surface of many immune cells, play an important role in their function. Chemokines are small proteins that bind to these receptors and control the movement and behavior of white blood cells.

Neanderthal-derived genetic locus influences COVID-19 severity in humans

Researchers in the United States and Estonia have identified four genetic variants on a chromosome 3 haplotype that may be responsible for driving the association between this locus and the severity of coronavirus disease 2019 (COVID-19).

Pathogenic airway neutrophilia drives ARDS in Black patients with severe COVID-19 in case study

Researchers from the US used a systems immunology approach where they combined high-dimensional flow cytometry and multi-omics single-cell sequencing analyses of immune profiles taken from the airways and matching blood samples of Black/AA patients.

What lessons have we learned over a year into the COVID-19 pandemic?

One of the pressing questions scientists are currently trying to answer is whether the current vaccines will remain effective against the emerging SARS-CoV-2 variants of concern. A new piece of research has been published in the journal Biomedicines, which discusses the knowledge we have gained thus far and the questions that researchers should address in future work.

Maternal SARS-CoV-2 infection imprints immune response in the newborn

A new bioRxiv* preprint reports the immunological footprint in the newborn left by maternal infection with SARS-CoV-2 during pregnancy.

Mast cell activation may underlie inflammation in severe COVID-19

A new preprint research paper posted to the medRxiv* server points to mast cells as major culprits in the etiology of severe and critical COVID-19. This could suggest suitable therapeutic and preventive interventions to reduce the morbidity and mortality of this viral illness.

New therapeutic approach developed to treat psoriatic arthritis

An international team of researchers, led by UC Davis Health, has developed a new therapeutic approach to treating psoriatic arthritis, a chronic inflammatory disease affecting the joints.

Research opens alternative therapeutic avenues for treatment of chronic pain

Building on previous findings, scientists have demonstrated that conolidine interacts with the newly identified opioid receptor ACKR3/CXCR7.

Antibody cocktail effectively inhibits SARS-CoV-2 in the rhesus macaque model

Researchers from the US tested the prophylactic potential of a combination of 2 mAbs administered 3 or 75 days before respiratory challenge in rhesus macaques. They used the rhesus macaque model to test the added benefit of combinatory parenteral administration of 2 high-affinity anti-SARS-CoV-2 mAbs - C144-LS and C135-LS. These mAbs were developed to neutralize the virus and tweaked to improve their pharmacokinetics.
