Hyperbaric Oxygen Therapy-What are the cellular mechanisms ?
Hyperbaric oxygen therapy (HBOT) exerts its effects through several cellular mechanisms:
-
Enhanced Oxygen Delivery: HBOT increases the partial pressure of oxygen in the blood, leading to higher oxygen availability at the cellular level. This supports cellular metabolism and energy production, particularly in hypoxic tissues.
-
Reduction of Oxidative Stress: By modulating the production of reactive oxygen species (ROS), HBOT helps balance oxidative stress. It can enhance antioxidant defenses, reducing cellular damage and inflammation.
-
Stem Cell Mobilization: HBOT has been shown to increase the number of circulating stem cells, which can contribute to tissue repair and regeneration.
-
Modulation of Inflammatory Pathways: HBOT influences immune cell function, promoting a shift from pro-inflammatory to
states. This includes the polarization of macrophages and the modulation of cytokine production. -
Angiogenesis and
Synthesis: HBOT stimulates the formation of new blood vessels (angiogenesis) and enhances collagen synthesis, which are crucial for wound healing and tissue repair. -
Cellular
and Repair: HBOT can interfere with cellular senescence, promoting cell cycle re-entry and reducing markers of senescence, thereby supporting tissue rejuvenation.
These cellular mechanisms collectively contribute to the therapeutic effects of HBOT, making it beneficial for a variety of medical conditions.
