Study reviews recent insights into the pathogenesis of feline leukemia virus infection

Feline leukaemia virus (FeLV) is a gammaretrovirus that occurs worldwide in domestic cats, as well as small wild cats. It is associated with various serious, and sometimes fatal, diseases including anaemia, immunosuppression and certain cancers

Allergic immune response against bacteria is not pathological but protective

Allergy is one of the most common diseases in Europe, it is estimated that more than 150 million Europeans suffer from recurring allergies and by 2025 this could have increased to half of the entire European population.

Brain inflammation seen in fatal COVID-19 cases

Now, a new study by researchers at the Barts Health NHS Trust and the University of Cambridge in the United Kingdom shows that some patients develop neurological complications tied to COVID-19.

Study reveals how B cells react to SARS-CoV-2

In an exciting immunological medRxiv preprint paper, researchers from Germany and Russia analyzed adaptive immune response in severely affected patients with coronavirus disease (COVID-19). They demonstrated a protracted immune reaction characterized by egress of B lymphocytes into the blood.

Researchers receive $1.9 million federal grant to find Lyme disease vaccine

Pesky, yet dangerous ticks are no longer latching exclusively onto hunters and outdoor enthusiasts. Milder winters and disrupted habitats have driven them out of the woods, with Lyme disease cases in the United States tripling since the late 1990s.

Researchers discover a new way to limit inflammation from adjuvants in vaccines

Adjuvants are a key ingredient of many modern vaccines, working to unleash an immune response that helps protect the body from disease. Many scientists believe that adjuvants are they key to developing new kinds of vaccines for hard-to-vaccinate viruses, like HIV.

Scientists shed new light on gene regulatory pathways activated by stress hormone

Scientists have long known that chronic stress experienced early in life, or even chronic prenatal exposure to maternal stress hormones in the womb, can shorten lifespan and contribute to age-related chronic diseases like arthritis, asthma, cancer, cardiovascular disease, diabetes and even mental illness later in life -- long after the source of stress has been removed.

Exercise and diet are more important than ever with virus at large

If your life these days is anything like mine, a pre-pandemic routine that included regular exercise and disciplined eating has probably given way to sedentary evenings on a big chair, binge-watching reruns of your favorite TV series while guzzling chocolate ice cream or mac 'n' cheese.

Host gene editing main driving force of SARS-CoV-2 mutations

A new study published on the aRxiv preprint server in September 2020 shows that the host immune response, mediated by two RNA editors, causes the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to adapt and change strain characteristics.

Scientists explain why men are at higher risk from COVID-19

Published in the journal PLOS Biology, the study aimed to provide a better understanding of the mechanisms that drive the varying responses of the infected individuals among different patient demographics, including sex and age.

New combination therapy helps fight cancer

Radiation causes key changes to immune cells in kidney cancer tumors.T cells in tumors are expanded in blood shortly after radiation, then decrease.

'Molecular brake' on the immune system could be potential treatment target for severe COVID-19

Older people and people with underlying medical conditions are at particular risk of severe COVID-19. A group of researchers from Charité - Universitätsmedizin Berlin have discovered one possible reason for this vulnerability.

Scientists develop a rapid, reliable and low-cost COVID-19 antibody test

Robust and widespread antibody testing has emerged as a key strategy in the fight against SARS-CoV-2, the virus responsible for the COVID-19 pandemic.

Study reveals complex immunology behind MIS-C in children with COVID-19

In a recent paper published in the prestigious journal Cell, researchers from Sweden and Italy show that inflammatory response in Multisystem Inflammatory Syndrome in Children associated with coronavirus disease (COVID-19) differs from the cytokine storm found in severe acute illness, involving autoantibodies at the same time and sharing several features with Kawasaki disease.

Tel Aviv University receives philanthropic grant from 3M for COVID-19 vaccine research

Science-based technology company 3M has awarded a significant philanthropic research grant of $400,000 to the Shmunis School of Biomedicine and Cancer Research at Tel Aviv University to advance scientific knowledge in the global response to the COVID-19 pandemic.

The T cell responses in COVID-19 recovered individuals

A recent study demonstrates that functional CD4+ and CD8+ T cells specifically targeting the entire proteome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain active in individuals who have recovered from severe or mild coronavirus disease 2019 (COVID-19). Moreover, the magnitude of T cell response is correlated with the antibody response. The study is published in the journal Nature Immunology.

Study finds strong T cell responses in patients recovered from COVID-19

Oxford University researchers have found that natural infection with COVID-19 produces a robust T cell response, including inducing T cell ‘memory’ to potentially fight future infections.

Antibody-mediated platelet death linked to COVID-19 severity

A new study by University of Tuebingen researchers shows the strong association between platelet apoptosis and the thrombotic manifestations that may underlie critical COVID-19 illness.

Novel markers may predict patient response to immune checkpoint inhibitors

For many individuals with different types of cancer, immune checkpoint inhibitors can effectively boost their immune system to fight their disease, but not all patients benefit from these medications.

First 'plug and play' brain prosthesis demonstrated in a person with paralysis

In a significant advance, UC San Francisco Weill Institute for Neurosciences researchers working towards a brain-controlled prosthetic limb have shown that machine learning techniques helped an individual with paralysis learn to control a computer cursor using their brain activity without requiring extensive daily retraining, which has been a requirement of all past brain-computer interface efforts.
