T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on ...

Researchers have engineered Arabidopsis plants that emit visible light when their immune defenses switch on, creating a living sensor that tracks how plants fight pathogens in real time. The work, ...

Pulmonary expert Noah Greenspan, DPT, discusses long COVID, early pandemic uncertainty, and how vaccination may help reduce ...

A fourth dose of bivalent or monovalent BA.1-adapted BNT162b2 vaccines was safe and elicited robust neutralizing responses in adults aged 18 to 55 years.

Plant immunity is largely initiated at the cellular level, with each cell capable of autonomous detection and response, while ...

Northwestern Medicine scientists have discovered that specialized immune cells within the glioblastoma tumor metabolize fructose to suppress immune responses and promote tumor growth, reports a study ...

What impact does a viral infection have on our memory, attention, and concentration? The COVID-19 pandemic has reignited interest in this question, which has now been extended to other infections such ...

RA patients on upadacitinib and methotrexate showed robust antibody and T-cell responses to the recombinant zoster vaccine over 60 weeks. The vaccine maintained a satisfactory humoral response in 71.4 ...
