Novel peptide-drug conjugate enhances the efficacy of immunotherapy in preclinical cancer models

A peptide-drug conjugate that targets the acidic environment of cancer cells enhanced the efficacy of immune checkpoint inhibitors in preclinical cancer models, according to results presented at the AACR-NCI-EORTC Virtual International Conference on Molecular Targets and Cancer Therapeutics, held October 7-10, 2021.

First of its kind ‘living medicine’ designed to treat antibiotic-resistant bacteria on medical implants

Researchers at the Centre for Genomic Regulation and Pulmobiotics S.L have created the first 'living medicine' to treat antibiotic-resistant bacteria growing on the surfaces of medical implants. The researchers created the treatment by removing a common bacteria's ability to cause disease and repurposing it to attack harmful microbes instead.

Novel strategy for in vitro cell-selective protection has potential for use in adoptive cell therapy

Adoptive cell therapy (ACT) is an emerging powerful cancerimmunotherapy, which includes a complex process of genetic modification, stimulation and expansion. During invitroorexvivomanipulation, sensitive cells are inescapably subjected to harmful external stimuli. Although a variety ofcytoprotectionstrategies have been developed, their application on ACT remains challenging.

Solar exposure guidelines for optimal vitamin D synthesis may need to be revised, study suggests

Previously published solar exposure guidelines for optimal vitamin D synthesis based on a study of skin samples may need to be revised, according to new research published today in PNAS.

New 3D pancreatic cancer model could be used to develop and test targeted treatments

An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments.

Study points to a possible new approach for treating MRSA superbug

A study released in STEM CELLS Translational Medicine, by researchers at the Baker Institute for Animal Health, part of Cornell University's College of Veterinary Medicine, Ithaca, N.Y., details in a relevant ex vivo model how treating wounds with the secretion of a type of stem cell called mesenchymal stromal cell (MSC) effectively reduced methicillin-resistant Staphylococcus aureus – better known as MRSA viability and stimulated the surrounding skin cells to build up a defense against the bacterial invader.

Antiviral compound RG10 acts via intracellular SARS-CoV-2-ER dynamics

A new study describes a small molecule referred to as RG10 that may have potent antiviral activity against SARS-CoV-2 in human cells.

New artificial blood vessel platform for predicting organ transplant rejection

Organ transplantation involves the transplantation of organs from donors as a means to treat disease or injury, but there is a shortage of organs available for donation compared to the demand for organ transplantation.

Durable highly protective T cell response to AAV-spike vaccine against COVID-19 pneumonia in mice

New research, available as a preprint on the bioRxiv* server, has focused on the role played by T cell immunity, particularly CD8+ cytotoxic T cells, on preventing lethal infection with SARS-CoV-2 in mice infused with peptide-loaded antigen-presenting dendritic cells (DCs).

Response to a third SARS-CoV-2 vaccine dose amongst immunocompromised

In a research paper recently uploaded to the preprint server medRxiv* by Schrezenmeier et al. (August 12th, 2021) the potential benefit of three vaccine doses in either a homogenous or heterogeneous dosing regimen amongst kidney transplant patients is assessed, finding that the search for viable vaccination approaches amongst these patients remains an urgent medical need.

Study offers new insights on coronary microvascular dysfunction

New research has shown abnormalities in the tiny blood vessels of human hearts in regions well beyond the large arteries with atherosclerotic blockages that trigger the need for stents or bypass surgery.

Study shows COVID-19 organ-specific outcomes depend on anti-spike glycoprotein antibodies

A recent study from the University of Rochester reveals how the biodistribution kinetics and the affinity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for many different organs in the human body can be affected by antibodies targeting viral spike glycoprotein. The paper is currently available on the bioRxiv* preprint server while it undergoes peer review.

Study associates feelings of discrimination and low status with long COVID-19 symptoms

A recent study, released as a preprint on the medRxiv* server, examines the correlation of these symptoms with the patient’s socioeconomic status (SES) and perception of social discrimination, along with other social factors. The researchers found that the first two factors are associated strongly with long-term symptoms of COVID-19.

Can memory T cell responses to seasonal coronaviruses protect against severe COVID-19?

In a recent study published in the journal Science Immunology, scientists have revealed that the presence of CD8+ T cells against conserved epitopes of seasonal coronaviruses is associated with mild coronavirus disease 2019 (COVID-19). These immune cells exhibit a memory phenotype and provide protection against severe disease.

Researchers discover new class of drugs that inhibits a 'master switch' in mantle cell lymphoma

A new class of drugs that inhibits a "master switch" involved in the vast majority of cases of mantle cell lymphoma (MCL), a fatal subtype of non-Hodgkin's lymphoma, has been discovered by researchers at Mount Sinai.

KIYATEC’s test results accurately predict treatment response in recurrent high-grade glioma patients

KIYATEC, Inc. announced today the publication of new peer-reviewed data that establishes clinically meaningful prediction of patient-specific responses to standard of care therapy, prior to treatment, in newly diagnosed glioblastoma (GBM) and other high-grade glioma (HGG) patients.
