A common dietary fiber promotes allergy-like immune responses in preclinical studies
by Weill Cornell Medical College Color-enhanced goblet cells (dark purple) in lung epithelium. Credit: Dr. Mohammad Arifuzzaman and Dr. David Artis A type of dietary fiber called inulin, commonly used in health supplements and known to have certain anti-inflammatory properties, can also promote an allergy-related type of inflammation in the lung and gut, and other...
Study reveals new mode of triggering immune responses
by Weill Cornell Medical College Confocal microscopy image shows that DNA (green) and the chemokine CXCL4 (red) colocalize (indicated by yellow areas) during inflammatory responses in the skin. Credit: Barrat lab Small proteins, called chemokines, that direct immune cells toward sites of infection can also form DNA-bound nanoparticles that can induce chronic, dysfunctional immune responses, according...

Single-shot COVID-19 vaccine generates robust immune responses against COVID-19 variants
by Jacqueline Mitchell, Beth Israel Deaconess Medical Center Credit: Pixabay/CC0 Public Domain In the three months since Johnson & Johnson’s COVID-19 vaccine received emergency use authorization from the U.S. Food and Drug Administration, more than 10 million Americans have received the vaccine, according to the Centers for Disease Control and Prevention. The single-shot viral vector vaccine—developed...
Delivering vaccines directly to the lungs can boost immune responses to respiratory infections or lung cancer: study
by Sarah McDonnell, Massachusetts Institute of Technology Antigen peptides (green) from the novel albumin-binding vaccine (amphiphile, right column) were better retained in the lungs and draining lymph nodes of mice than the control vaccine (soluble, left column).

Immune responses during embryo development could increase risk of schizophrenia
by Ingrid Fadelli , Medical Xpress Human Embryo. Credit: Ed Uthman, MD/Wikipedia Past research has often highlighted the effects that immune activation in pregnant women can have on the development of human embryos, for instance increasing the risk of a child developing psychiatric disorders later in life. The neural mechanisms underpinning these effects, however, remain largely unclear....
