The term "probiotic" is limited. A new term, "immunobiotics," is proposed for microbes that enhance health by modulating mucosal immune responses, distinct from those with local effects.

Area of Science:

  • Microbiology
  • Immunology
  • Gastroenterology

Background:

  • The term 'probiotic' lacks scientific rigor due to poorly characterized microbes and unclear mechanisms.
  • Existing research suggests some probiotics activate the common mucosal immune system.
  • A need exists for a term differentiating microbes that systemically influence immunity.

Purpose of the Study:

  • To address the limitations of the term 'probiotic'.
  • To propose a new term for microbes that promote health via mucosal immune mechanisms.

Main Methods:

  • Review of current scientific literature on probiotics and mucosal immunity.
  • Analysis of clinical and animal model studies on microbial-immune interactions.

Main Results:

  • Probiotics can stimulate gut antigen-presenting cells, promoting protection and regulating immune responses.
  • The current definition of 'probiotic' does not fully capture microbes with systemic immune-modulating effects.

Conclusions:

  • A new term is needed to accurately describe bacteria that drive mucosal immune mechanisms for health.
  • The term 'immunobiotics' is suggested for microbes that promote health by activating systemic mucosal immunity.
