Combining inhibitor drug with immunotherapy agent improves response in cancer patients

Combining a histone deacetylase inhibitor drug with immunotherapy agents is safe, and may benefit some patients with advanced cancers that have not responded to traditional therapy, according to results of a phase 1 clinical trial led by researchers at the Johns Hopkins Kimmel Cancer Center, Bloomberg~Kimmel Institute for Cancer Immunotherapy and several other centers including University of Pittsburgh Cancer Institute, Yale Cancer Center and City of Hope in Los Angeles, which participated in study enrollment, and the University of Southern California and University College Cork in Ireland, which collaborated on analysis of the data.

Penn researchers reveal complex details of T-cell responses to mRNA COVID-19 vaccines

Messenger-RNA (mRNA) vaccines against the coronavirus that causes COVID-19 provoke a swift and strong response by the immune system's T cells-;the heavy armor of the immune system-;according to a study from researchers in the Perelman School of Medicine at the University of Pennsylvania.

Research suggests toll-like receptor 4 appears to play role in severe COVID

A group of researchers re-evaluated their previously proposed hypothesis, which stated that the TLR4 activated by the spike glycoprotein S1 domain increases ACE2 expression and, thereby, aids in COVID-19 infection.

Certain intestinal bacteria induce cross-reactive IgA responses to the SARS-CoV-2 spike RBD

A new study finds that human gut bacteria can induce antibodies of the immunoglobulin A (IgA) subtype that cross-react with the SARS-CoV-2 spike RBD.

World-first trial of third dose COVID-19 booster vaccine shows improved protection in transplant patients

Scientists with the Ajmera Transplant Centre at UHN have conducted a first-in-the-world randomized placebo-controlled trial of third dose COVID-19 booster vaccine for transplant patients that shows substantially improved protection.

Enzyme acts as a sensor to find the hiding spots of viruses

While some types of RNA viruses cloak themselves to hide inside a cell and create copies of themselves, a "detective enzyme" might be attuned to their whereabouts. A slight variation in their genomic code gives some people's cells the capacity to produce this sensor.

Understanding how to regulate key enzyme may lead to new treatments for cancers, viral infections

A new study led by University of California, Irvine (UCI) researchers identifies two ways in which APOBEC3A-; a vital enzyme that is responsible for genetic changes resulting in a variety of cancers while protecting our cells against viral infection-;is controlled.

‘I don’t want to risk my life for a paycheck’: Immunosuppressed people grapple with returning to work

Elizabeth Groenweghe got a kidney transplant 14 years ago. She now takes several medications to prevent her body from rejecting her transplant organ. But these medications also weaken her immune system, putting her at higher risk of becoming seriously ill if she catches covid-19.

L452R mutations may have triggered the emergence of several COVID-19 variants

Most of the recently risen coronavirus variants of interest or concern -- delta, kappa, epsilon, iota and lambda -- are universally carrying a mutation in amino acid L452 of the Spike protein that helps the virus bind to host cells.

CDC recommends additional dose of mRNA COVID-19 vaccine in moderately to severely immunocompromised people

Today, I signed CDC's Advisory Committee on Immunization Practices' (ACIP) recommendation that endorsed the use of an additional dose of COVID-19 vaccine for people with moderately to severely compromised immune systems after an initial two-dose vaccine series.

Study finds four circulating miRNAs which could effectively inhibit SARS-CoV-2 replication

In a new study, Chen-Yu Zhang's group from Nanjing University presents a rather striking finding that four circulating miRNAs, which are high in healthy people and much lower in older people and diabetic patients, could effectively inhibit SARS-CoV-2 replication by directly targeting the S protein.

Researchers map the impact of Covid-19 on the mental well-being of Israelis

During the six weeks between the end of the first COVID-19 outbreak in Israel and the beginning of the second one (late April to early June of 2020), researchers at the Weizmann Institute of Science initiated a study that encompassed more than 12,000 responses from nearly 5,000 respondents to digital questionnaires, in an attempt to assess and understand the mental toll of the pandemic on the country's adult population.

Nanotechnology may help improve treatment for colorectal cancer and melanoma

University of Arizona Health Sciences researchers recently completed a study that has the potential to improve cancer treatment for colorectal cancer and melanoma by using nanotechnology to deliver chemotherapy in a way that makes it more effective against aggressive tumors.

UC San Diego scientists develop new method to keep cultured cells healthy

Hematopoietic stem cells — the precursors to blood cells — have been notoriously difficult to grow in a dish, a critical tool in basic research.

COVID-19 risks likely to shift from older adults to younger children

Within the next few years, as the SARS-CoV-2 virus becomes endemic in the global population, COVID-19 may behave like other common-cold coronaviruses, affecting mostly young children who have not yet been vaccinated or exposed to the virus, according to new modeling results.

Two-arm molecule can deplete cancer-protecting cells to promote immune responses against tumors

A two-arm molecule can effectively deplete cancer-protecting cells inside tumors, allowing the immune system to fight off tumors without becoming overactive. The finding, published online in Science Translational Medicine, could lead to new types of cancer immunotherapies.
