T cells are a crucial part of the human adaptive immune system. In response to a foreign invader in the body, various subsets of T cells are responsible for several functions that include killing infected cells and secreting signaling molecules called cytokines that tell other immune cells where to go and what to do. Different […]
A new method for generating metabolic profiles of single cells
Scientists from the European Molecular Biology Laboratory (EMBL) and the German Cancer Research Center (DKFZ) have presented a new method for generating metabolic profiles of individual cells. The method, which combines fluorescence microscopy and a specific form of mass spectroscopy, can analyze over a hundred metabolites and lipids from more than a thousand individual cells […]
Critical cell process shown to be missing in humans
Patients with a unique cellular disorder are helping researchers understand a series of health complications better. For the first time, researchers led by Newcastle University, UK have identified a group of patients with neurological disease who lack a critical cell process called autophagy. The work is published today in the New England Journal of Medicine. […]
Stem cell transplant reviewed for peripheral T-cell lymphoma
(HealthDay)—For patients with refractory or relapsed peripheral T-cell lymphoma (R/R-PTCL), three- and five-year overall survival (OS) and progression-free survival (PFS) are similar with allogeneic or autologous hematopoietic stem cell transplant (HSCT), but transplant-related mortality (TRM) is higher with allogeneic HSCT, according to a review published online May 27 in JAMA Network Open. Jun Du, M.D., […]
Cell encapsulation could enhance antiviral vaccines
Immunotherapy techniques developed in oncology to combat cancerous cells have great potential for fighting viruses. A research team from the University Hospitals of Geneva (HUG) and the University of Geneva (UNIGE), in Switzerland, in collaboration with MaxiVAX, a spinoff of both institutions, developed an innovative technology called “cell encapsulation”. Originally designed to stimulate immunity to […]
Machine learning technique detects epigenetic drivers of cancers
Scientists have made major advances in understanding and developing treatments for many cancers by identifying genetic mutations that drive the disease. Now a team led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and the New York Genome Center (NYGC) has developed a machine learning technique for detecting other modifications to DNA that have a similar […]
Combination of 2-Photon 3D-printer and bioink allows precise, direct printing of living cells
The combination of a 2-Photon 3D-printer with an innovative hydrogel-based bioink allows the direct printing of 3D structures containing living cells at both the meso- and microscale. Developed by UpNano GmbH (Vienna, Austria), the NanoOne Bio is a printer based on the successful NanoOne range of laser-powered 2-Photon 3D-printers that are able to build structures […]
Could N protein-based COVID-19 vaccines hinder SARS-CoV-2's NK cell inhibition?
When a virus invades an individual, both innate and adaptive immunity play crucial roles. The successful viral pathogens can antagonize these immune pathways with genes that inhibit the key players in the immune system. The coronavirus disease 2019 (COVID-19) pandemic is caused by the novel beta coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It […]
CD40 drug before surgery can benefit patients with early-stage pancreatic cancer
Giving early-stage pancreatic cancer patients a CD40 immune-stimulating drug helped jumpstart a T cell attack to the notoriously stubborn tumor microenvironment before surgery and other treatments, according to a new study from researchers in the Abramson Cancer Center (ACC) at the University of Pennsylvania. Changing the microenvironment from so-called T cell "poor" to T cell […]
More new SARS-CoV-2 variants are highly likely
In a recent report posted to the bioRxiv* preprint server, researchers from the United Kingdom and Uganda reveal unique protein features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) relative to other representatives of Sarbecoviruses. The causative agent of the coronavirus disease 2019 (COVID-19), SARS-CoV-2, belongs to the Betacoronavirus genus and Sarbecovirus subgenus of the […]
