MR-guided focused ultrasound can safely deliver antibody therapy to Her2-positive brain metastases

In a first-in-world clinical trial, researchers at Sunnybrook Health Sciences Centre in Toronto, Canada, have demonstrated that magnetic resonance (MR)-guided focused ultrasound can be used to safely deliver antibody therapy to breast cancer that has metastasized to the brain.

Non-invasive optical probe reveals the complex changes in tumors after immunotherapy

Johns Hopkins University engineers are the first to use a non-invasive optical probe to understand the complex changes in tumors after immunotherapy, a treatment that harnesses the immune system to fight cancer.

COVID-19 linked to newborn complications

A recent study discusses whether pregnant women with the COVID-19 are at a higher risk for poor outcomes for themselves and their babies.

More than half of COVID-19 survivors experience "long COVID", researchers say

More than half of the 236 million people who have been diagnosed with COVID-19 worldwide since December 2019 will experience post-COVID symptoms - more commonly known as "long COVID" - up to six months after recovering, according to Penn State College of Medicine researchers.

Anti-rheumatic drug as a potential candidate for treating COVID-19

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produces inflammatory cytokine storms. But an FDA-approved anti-rheumatic drug, Auranofin, used to treat autoimmune and infectious diseases, may also help serve as an antiviral treatment for COVID-19 infection.

IgA antibodies play a key role in keeping the intestinal flora in balance

The bacteria living in the intestine consist of some 500 to 1000 different species. They make up what is known as the intestinal flora, which plays a key role in digestion and prevents infections.

Study finds nearly 42,000 sources of toxic "forever chemicals" that could be polluting water bodies

A new study by Environmental Working Group scientists finds almost 42,000 potential sources of the toxic "forever chemicals" known as PFAS that could be polluting surface water or drinking water in communities across the U.S.

Researchers uncover how cancer cells use sugar residue to evade the immune system

A team of South Dakota State University chemistry researchers uncovered how cancer cells utilize a simple sugar residue to disguise themselves from the immune system. What they learned will help scientists develop more effective cancer therapeutics.

Novel therapy approach could stop tumor growth

The immune system protects the body from cancer. To protect healthy body cells from its own immune system, they have developed a protective shield: the protein CD47 is a so called "don't eat me" signal, which tells the immune cells to stand back.

Rapid measurement of SARS-CoV-2 spike T-cells

Researchers measure SARS-CoV-2 T-cell responses in individuals vaccinated or in those who developed immunity from a prior natural infection.

Researchers identify how estrogens can influence the growth of melanoma

The link between estrogens and breast cancer has long been defined, but a Duke-led research team has identified how these hormones can also influence the growth of other cancers, notably melanoma.

Vaccinated children induced significantly higher antibody titers than naturally SARS-CoV-2 infected children

A recent preprint discusses the antibody response to the nucleic acid vaccines against SARS-CoV-2 when administered to children aged 7-11 years.

Nucleoside modifications suppress the potential of RNA to activate dendritic cells

A new paper shows that human TLR3, TLR7, and TLR8 receptors are activated with naturally occurring RNA, but this is eliminated once modified nucleosides such as m5C, m6A, m5U s2U, or pseudouridine are incorporated.

A new bacterial two-hybrid assay to study SARS-CoV-2 interactome

Recently, scientists have developed a bacterial two-hybrid (B2H) system to study the PPIs of SARS-CoV-2 in a heterologous non-eukaryotic system. This study is available on the bioRxiv* preprint server. Put simply, the B2H system could be used to analyze the SARS-CoV-2 proteome.

Drug developed at Duke is approved by FDA as only therapy for congenital athymia

The phone rang into the pediatric unit that Louise Markert, M.D., Ph.D., was staffing as a junior faculty member in 1991. Had she not answered, there would have been little hope for the more than one hundred patients who were subsequently treated.

Small set of beneficial bacterial strains linked to effectiveness of fecal microbiota transplants

The effectiveness of fecal microbiota transplantation (FMT) in treating ulcerative colitis depends on a small set of beneficial bacterial strains, suggests a new study from researchers at Weill Cornell Medicine and NewYork-Presbyterian.

Delta variant exhibits immune evasion, enhanced cell entry, and augmented syncytium formation

Researchers addressed the question of using reporter particles pseudotyped with the S protein of SARS-CoV-2, which are suitable tools to examine SARS-CoV-2 neutralization antibodies.

Vaccine-induced memory B cells can recognize SARS-CoV-2 variants

Researchers have been investigating the effect that memory B cells produced in individuals who have received an mRNA vaccine have against SARS-CoV-2 variants.

Kidney transplant patients are more susceptible to harmless bacterium, finds study

It's a pervasive bacterium found in soil and water that rarely causes disease, but a new national review of nocardia infection in people who have had a kidney transplant shows that when it occurs it most commonly causes pneumonia and brain abscess, and reminds their physicians to stay on the lookout for it, investigators say

Research finds different antibody responses following COVID vaccination and natural infection

A new study published in the journal Nature attempted to investigate memory B cell evolution 5 months after vaccination with mRNA vaccines such as Moderna (mRNA-1273) or Pfizer-BioNTech (BNT162b2) in SARS-CoV-2 naïve individuals. The study explored various aspects of memory B cell antibody response like neutralizing response, affinity, epitope targeting, and neutralizing breadth.
