DOI: 10.1016/j.immuni.2023.12.006How does your immune system decide between fighting invading pathogens now or preparing to fight them in the future? Turns out, it can change its mind. Every person has 10 million to 100 million unique T cells that have...

Detecting pathogens faster and more accurately by melting DNA
by Ioana Patringenaru, University of California – San Diego Researchers use this chip to analyze the microbes present in whole blood samples. Credit: David Baillot/University of California San DiegoA new analysis method can detect pathogens in blood samples faster and more accurately than blood cultures, which are the current state of the art for infection diagnosis....
New vaccine design uses immunity against influenza to offer faster protection against emerging pathogens
by Iqbal Pittalwala, University of California – Riverside Credit: CC0 Public DomainAfter COVID vaccination, it usually takes weeks for our bodies to develop protective antibody responses. Imagine, however, a vaccine that speeds up the production of antibodies against SARS-CoV-2, the virus that spreads COVID-19. A research team led by Rong Hai, an associate professor of microbiology...
China says a surge in respiratory illnesses is caused by flu and other known pathogens
A man carriers a child walk out from a crowded holding room of a children’s hospital in Beijing on Oct. 30, 2023. A surge in respiratory illnesses across China that has drawn the attention of the World Health Organization is caused by the flu and other known pathogens and not by a novel virus, the...
Fresh risks in ready-to-eat produce: Study reveals how common pathogens lurk in our salads
By Tarun Sai LomteNov 6 2023Reviewed by Susha Cheriyedath, M.Sc. In a recent study published in the journal Food Microbiology, researchers summarized the evidence on interactions of enteric bacterial pathogens with ready-to-eat (RTE) fruits and vegetables. Fruit and vegetable consumption is associated with diverse health benefits and has substantially increased from 1960 to 2019, along...
Discovery of a new antibiotic against resistant pathogens
UNIVERSITY OF BASEL For a long time, antibiotics were considered a silver bullet against bacterial infections. Over time, many pathogens have adapted to resist antibiotics, so the search for new drugs is becoming increasingly important. An international team of researchers including scientists at the University of Basel, has now discovered a new antibiotic by computational...
Immunologists at the University Medical Center Magdeburg have deciphered a new role of nitric oxide in the defense against pathogens

MÜLLER, HEAD OF THE INTRAVITAL MICROSCOPY OF INFECTION AND IMMUNITY GROUP, INSTITUTE OF MOLECULAR AND CLINICAL IMMUNOLOGY, FACULTY OF MEDICINE, OTTO VON GUERICKE UNIVERSITY CREDIT: CHRISTIAN MORAWE Nitric oxide (NO) occurs naturally in the human body as a messenger substance. It is considered an all-rounder, as it performs...
Pathogens in the mouth induce oral cancer
by Public Library of Science Dental care. Pathogens found in tissues that surround the teeth contribute to a highly aggressive type of oral cancer, according to a study published 1st October in the open-access journal PLOS Pathogens by Yvonne Kapila of the University of California, San Francisco, and colleagues. In addition, the study showed that oral cancer formation...
COVID-19 and mRNA Vaccines—First Large Test for a New Approach
On January 10, Chinese researchers posted the novel coronavirus’ RNA sequence on a preprint server. Immediately, scientists who study genetic vaccines turned their efforts to the emerging pathogen that causes coronavirus disease 2019 (COVID-19). They knew that rapid response genetic platforms could shave precious weeks to months off development, crucial during a pandemic. They were...
Subtypes and developmental pathways of innate T cells identified
POHANG UNIVERSITY OF SCIENCE & TECHNOLOGY (POSTECH) INNATE T CELLS HAVE ANALOGOUS EFFECTOR SUBSETS. view more CREDIT: YOU JEONG LEE, SANGUK KIM (POSTECH) There are memory cells that remember previously encountered pathogens and help to react quickly and strongly when exposed to them again. The developmental process of strong immune cells that make these memory...
