How adrenaline-related signals regulate immune response by daily movement of immune cells through lymph nodes

AI simplified

Abstract

Lymphocyte egress from lymph nodes is reduced at night due to inputs from adrenergic nerves.

  • Diurnal variations in lymphocyte recirculation through lymph nodes are linked to the time of day.
  • Neural inputs to β-adrenergic receptors on lymphocytes affect their movement, with fewer lymphocytes leaving lymph nodes at night.
  • Increased lymphocyte accumulation in lymph nodes at night correlates with enhanced antibody responses following immunization.
  • The dependence of humoral immune response on β-adrenergic signaling suggests a novel mechanism for immune system rhythms.
  • Stopping lymphocyte recirculation through lymph nodes diminishes the observed diurnal variation in immune responses.
