A recent study by Johns Hopkins Medicine researchers provides evidence that CD4+ T lymphocytes—immune system cells also known as helper T cells—produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at […]
Immune rejection is one of the biggest obstacles to cell therapy. To solve this problem, researchers have been investigating iPS cells that have been gene edited so that they can evade the immune system. While this concept is theoretically possible, there is limited evidence that it works in species resembling humans. A new study by […]
When microorganisms—such as bacteria or viruses—infect us, our immune system jumps into action. It’s highly trained to sense and eliminate infections and clear up any damage caused by them. It’s typically assumed our immune systems work the exact same way regardless of whether an infection occurs during the day or at night. But research spanning […]
Millions of people suffer from psoriasis, a chronic, autoimmune disorder that causes scaly patches on the skin and often precedes psoriatic arthritis. While no cure exists, treatments range from topical creams to injected medications that block inflammation. To improve treatment options, scientists need to better understand the dysregulation of the immune system that leads to […]
With COVID-19 cases rising with each passing day, having a good immune system holds immense importance. Sure, it might be just two fluids swimming around your body, namely blood and lymph. But, given the circumstances, they are the only things keeping you alive and healthy. While these two fluids are hard at work protecting your body […]
Respiratory viruses such as SARS-CoV-2 (causing COVID-19) can often catalyze an overactive immune response that leads to a life-threatening cycle, known as a cytokine storm. Analyzing cytokine responses from patients infected with SARS-CoV-2 and similar common respiratory viruses has unearthed glaringly important differences in how SARS-CoV-2 affects cytokines compared to other common respiratory viruses. The […]

Pharmaceutical giant Johnson & Johnson on Wednesday published early data for its coronavirus vaccine, showing a lasting immune response and tolerability among trial volunteers. According to the findings, published in the New England Journal of […]
UC San Francisco scientists have discovered a new way to control the immune system’s ‘natural killer’ (NK) cells, a finding with implications for novel cell therapies and tissue implants that can evade immune rejection. The findings could also be used to enhance the ability of cancer immunotherapies to detect and destroy lurking tumors. The study, […]
Researchers at the Kobe University Graduate School of Medicine have revealed that alterations in fetal microglia resulting from maternal inflammation could contribute towards the onset of developmental and psychiatric disorders. The research team including Ph.D. student Ozaki Kana and Professor Yamada Hideto from the Department of Obstetrics and Gynecology observed that infant mice that were […]
A comparison of two key research tools used by immunologists to study different types of T-cell receptor signals has identified important features of existing technologies that could allow scientists to better understand immune responses, in a new study led by scientists at the University of Birmingham. T cells form a crucial part of the immune […]
