The immune system is highly time-of-day dependent. Pioneering studies in the 1960s were
the first to identify immune responses to be under a circadian control. Only in the last …

Not 1 year has passed since the emergence of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19) …

The adaptive immune response is under circadian control, yet, why adaptive immune
reactions continue to exhibit circadian changes over long periods of time is unknown. Using …

Antibody responses to SARS-CoV-2 vaccines vary for reasons that remain poorly
understood. A range of sociodemographic, behavioural, clinical, pharmacologic and …

The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) is a global crisis with unprecedented challenges for public health …

The immune system is built to counteract unpredictable threats, yet it relies on predictable
cycles of activity to function properly. Daily rhythms in immune function are an expanding …

Background White blood cells (WBC) are commonly measured to investigate suspected
infection and inflammation in pregnant women, but the pregnancy-specific reference interval …

Circadian rhythms of approximately 24 h have emerged as important modulators of the
immune system. These oscillations are important for mounting short-term, innate immune …

Twenty-four-hour rhythms in immune parameters and functions are robustly observed
phenomena in biomedicine. Here, we summarize the important role of sleep and associated …

Background: Several studies have found an association between elevated neutrophil count
or neutrophil-to-lymphocyte ratio (NLR) in peripheral blood from patients with schizophrenia …
