New findings could help speed the treatment for UTIs in children

A study led by UT Southwestern and Children's Health researchers defines parameters for the number of white blood cells that must be present in children's urine at different concentrations to suggest a urinary tract infection (UTI).

SARS-CoV-2-derived mutant peptides hamper T cells' ability to recognize and destroy infected cells

A deep sequencing study of 747 SARS-CoV-2 virus isolates has revealed mutant peptides derived from the virus that cannot effectively bind to critical proteins on the surface of infected cells and, in turn, hamper activation of CD8+ killer T cells that recognize and destroy these infected cells.

Researchers develop mutant gene-targeted immunotherapy approach to fight cancers

A novel targeted immunotherapy approach developed by researchers at the Ludwig Center, the Lustgarten Laboratory, and Bloomberg~Kimmel Institute for Cancer Immunotherapy at the Johns Hopkins Kimmel Cancer Center employs new antibodies against genetically altered proteins to target cancers.

HSE researchers discover genetic predisposition to COVID-19 severity

HSE University researchers have become the first in the world to discover genetic predisposition to severe COVID-19. The results of the study were published in the journal Frontiers in Immunology.

SHREK proteins mediate broad spectrum antiviral host immunity, including against SARS-CoV-2

A new preprint posted to the bioRxiv server demonstrates that similar mucins and mucin-like proteins cannot only suppress HIV-1 infectivity via blockage of viral attachment to the host cells but can block infection by multiple enveloped viruses.

Study explains why people of African descent are less likely to find bone marrow donors

A paper by a multidisciplinary team of scientists affiliated with various Brazilian institutions, including the University of São Paulo (USP) and the National Cancer Institute (INCA), shows that people of African descent are less likely to find a donor in the National Register of Voluntary Bone Marrow Donors (REDOME) than people with predominantly European ancestry.

Anakinra shows therapeutic potential in critically ill COVID-19 patients

A team of international scientists recently conducted an open-level clinical trial to investigate the effects of personalized immunotherapy on critically ill COVID-19 patients.

Circulating antiphospholipid antibodies drive endothelial cell activation in COVID-19

With the emergence of COVID-19 (coronavirus disease 2019), researchers have been closely investigating the complex interplay between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the human immune system, and COVID-19 disease severity.

High factor V levels linked to lymphopenia and weakened immunity in severe COVID-19

A new study suggests that factor V, a coagulation factor, is upregulated in a range of white blood cells in severe COVID-19. This increase is linked to the observed coagulopathy, lymphopenia and suppression of adaptive immunity in such patients.

Researchers develop new method for charting SARS-CoV-2 spike protein glycosylation

Researchers develop a novel, simple and affordable method for N-glycan fingerprinting based on enzymatic fluorescent glycan labeling and electrophoresis. This new method may help us understand important changes in glycosylation in the SARS-CoV-2 spike protein – something which could inform future therapeutic research.

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.

Headache as COVID-19 symptom could indicate milder disease, study finds

Researchers at the Hospital Universitario de La Princes in Madrid, Spain, found that patients with COVID-19 who developed headaches as an early symptom of infection had a milder illness and less risk of death.

SARS-CoV-2 mutations may evade T cell immunity

A potentially disturbing new study suggests that SARS-CoV-2 may be undergoing strategic mutations that affect the host immune capacity to recognize and combat the pathogen via T effector cells.

Study shows an inflammatory response in the mice brain is responsible for severe COVID-19

Researchers demonstrated that neuroinvasion and encephalitis caused by SARS-CoV-2 is associated with significant mortality in a special mouse model.

Epitope “megapools” could help determine role T cell immunity plays in COVID-19

Researchers in the United States and Australia have conducted a comprehensive analysis of the epitope recognition patterns associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in humans.

Reverse phenotyping shows reactive T cell profiles in SARS-CoV-2 infection

A new study appearing as a preprint on the medRxiv* browser in December 2020 employs reverse phenotyping technology to explore T cell responses in COVID-19.

Neutrophils may play a key role in COVID-19-related thrombosis

A team of researchers in Italy have published a study suggesting that rather than platelets, neutrophils could be playing the lead role in thrombotic complications associated with COVID-19.

Lipid storm in severe COVID-19 linked to high COX/LOX pathway activity

A potentially valuable new study discusses the role of lipids in the hyper-inflammatory phenomena that take place within the lungs of patients with severe or critical COVID-19. Involving a large variety of specialized lipids with biological activity, this process includes the generation and release of pro and anti-inflammatory lipids.

BCG vaccination appears to trigger cross-reactive SARS-CoV-2-specific T cell response

Recently, researchers from the Monash University and Monash Medical Centre, Clayton, Victoria, Australia, investigated whether peptide sensitization using BCG can produce cross-reactive T cells specific to SARS-CoV-2. Their study is published on the preprint server, medRxiv.
