Medical Xpress / The hunt is on for the telltale biomarker revealing precise degree of protection conferred by Moderna's mRNA vaccine
A new analysis is shedding light on antibody measurements that can help predict the protective capabilities of the Moderna mRNA vaccine for COVID-19.
Medical Xpress / Whether causing the common cold or COVID-19, coronaviruses deploy key enzymes to elude human immune response
The entire family of coronaviruses is equipped with multiple methods of evading the human immune system, and two new studies have taken a deep dive into how these viruses, including SARS-CoV-2, leverage highly specialized ...
Medical Xpress / Tiny protein apparently produces titanic impact in the lungs when encountering bacterial pneumonia
In the ongoing quest to discover which constituents of the immune system provide highly specified protection, scientists have found that a component of the innate immune system is endowed with the capability of guarding the ...
Medical Xpress / Killing is their job: Two studies analyze natural killer cells as they tackle the worst form of malaria
Scientists are unraveling the complex mystery underlying how the immune system mounts a potent defense against one of the world's most relentless killers—the deadly parasites that cause the worst form of malaria.
Medical Xpress / Tumor-infiltrating T cells may be markers to predict patients' responses to cancer immunotherapy
New insights into a population of tumor-infiltrating T cells may ultimately allow doctors to predict how patients will respond to checkpoint blockade immunotherapy, a form of cancer treatment with advantages that doctors ...
Medical Xpress / An antibody-based drug triggers rare inflammatory eye problems in macular degeneration patients
A drug approved in 2019 for macular degeneration apparently caused rare retinal side effects because of its interactions with the human immune system, two new studies have concluded.
Medical Xpress / Scientists shed new light on two proteins that exacerbate the progression of Parkinson's disease
Two proteins may be intimately linked to the progression of Parkinson's disease, a relentless and disabling neurodegenerative disorder that affects millions of people around the world.
Medical Xpress / Study: Experimental COVID shot made via egg-based technology elicits higher antibody proportion than mRNA vax
An experimental COVID-19 vaccine produced with technology based on a decades-old method, elicited virus-neutralizing antibodies in higher proportion than the amount induced by mRNA immunizations, a Phase 1 clinical trial ...
Medical Xpress / Human feces and urine contain a motherlode of health data: 'Smart toilets' detect daily fluctuations, serious disease
A disease-detecting toilet capable of a range of monitoring and surveillance activities could soon be reality, and while the device may test for everything from how fast your urine flows to reporting on your vital signs, ...
Phys.org / Scientists decipher how non-resistant forms of Staph aureus thwart antibiotics, almost like a superbug
Staphylococcus aureus (S. aureus) has a slew of surprises in its bag of dirty tricks and among the most puzzling has been the ability of non-resistant forms of the bacteria to emerge unscathed, even after exposure to high ...
Medical Xpress / A flurry of RSV vaccine research may result in a protective immunization in the not-too-distant future
A new analysis of how the immune system responds to both older and newer investigational vaccines for respiratory syncytial virus—RSV—will help inform the ultimate translation of an immunization from the laboratory to actual ...
Medical Xpress / Evolutionary history of SARS-CoV-2 leads to a universal vaccine already being tested in animal models
By taking inspiration from the evolutionary history of SARS-CoV-2 itself, scientists in China have crafted a new vaccine that, at least in animal models, provides protection against omicron and an array of its subvariants.
Medical Xpress / Experimental vaccine for deadly Marburg virus guards against infection with just a single dose
An experimental vaccine for Marburg virus—a deadly cousin of the infectious agent that causes Ebola—can protect large animals from severe infections for up to a year with a single shot, scientists have found in a new study.
Medical Xpress / How cancer cells die: Scientists explore new pathways of pyroptosis, killer kin of apoptosis
For anyone who has taken Biology 101, the concept of apoptosis—programmed cell death—is taught early in the course. You can't understand the life cycle of a cell without learning how they die.
Medical Xpress / An mRNA vaccine strategy under study to fight the flu—as a shot and intranasal spray
Messenger RNA vaccine technology, once an arcane area of research, became household terminology because of the COVID-19 pandemic, and now scientists are working on an mRNA flu vaccine strategy that, at least in this study, ...
