Extracts from two common wild plants block SARS-CoV-2 from entering human cells

Two common wild plants contain extracts that inhibit the ability of the virus that causes COVID-19 to infect living cells, an Emory University study finds.

Highly potent antibiotic candidate identified

One of the most promising new antibiotic candidates in decades is a powerful plant toxin that harbors a novel way of killing hazardous bacteria.

Researchers create CAR T cells for cancer immunotherapy

In CAR T-cell immunotherapy, T cells taken from the patient’s own blood are modified to contain so-called chimeric antigen receptors (CAR), which provide the T cells the ability to target and eradicate tumor cells.

Researchers analyze the involvement of immune cells in lung cancer survival

Lung cancer affects approximately 48,500 persons in the United Kingdom every year. New treatments are urgently needed because only around 20% of patients live 5 years after diagnosis, and it is the leading cause of cancer death.

Scientists identify factors that regulate the development of brain cells in a specific order

Researchers have identified the complete series of 10 factors that regulate the development of brain cell types in the visual system of fruit flies-; including in what order these neurons develop.

Transposons are a potential antibiotic resistance, a study reveals

According to biomedical engineers at Duke University, the physical mechanism that enables high doses of antibiotics to encourage the transmission of antibiotic resistance across bacteria is now identified.

Research develops novel ways to recreate totipotency by cellular reprogramming

Adult cells in our bodies can only produce cells of the same type. A skin cell, for example, can only produce skin cells and not muscle cells. This restricts the therapeutic potential of mature cells.

Researchers grow intestinal organoids to study why bats infected with viruses do not succumb to diseases

Experiments attempting to explain why bats can be infected with many viruses at a time without succumbing to diseases such as COVID-19-;knowledge that could help us to reduce the threat to humans of infectious disease-;have struggled until now with the fact that live wild bats make poor research subjects.

Researchers test a neoantigen-specific transgenic immune cell therapy for malignant gliomas

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

Tough protein connects directly with neurons to cause damaging inflammatory reaction in the brain

Neuroinflammatory diseases, including Alzheimer's disease and traumatic brain injury, have been linked to deposits of a tough protein known as fibrin, derived from the blood clotting factor fibrinogen.

Combining bacteriophages with antibiotics to treat antibiotic-resistant infections

Mycobacterium abscessus, a relative of the bacteria that cause tuberculosis and leprosy, is responsible for particularly severe damage to human lungs and can be resistant to many standard antibiotics, making infections extremely challenging to treat.

Researchers print new low-cost, reproducible cell co-cultivation system

Scientists of the MIPT Cell Signaling Regulation Laboratory have developed a new low cost reproducible system for the co-cultivation of cells. This system is based on a polymerized BSA membrane.

New test to detect substances that are harmful to the placenta and embryo

Researchers at ETH Zurich have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version is designed to help reduce the number of animal experiments.
