    Micro- and nanoplastics (MNPs) may accumulate in bone marrow, posing systemic health risks beyond gastrointestinal effects.

  • 2

    MNPs can disrupt osteoimmunological homeostasis, impairing bone formation and promoting osteoclastogenesis.

  • 3

    Potential mechanisms of MNP-induced bone toxicity include oxidative stress, NF-κB signaling, and gut microbiota dysbiosis.

  • 4

    Pediatric and geriatric populations may be particularly susceptible to the effects of MNP exposure on bone health.

  • 5

    The review emphasizes the need for incorporating osteoimmunological endpoints in future MNP risk assessments.
