    Oxygen levels significantly influence the proliferation and cytokine production of CD4+ memory T cells.

  • 2

    Physiologically healthy oxygen levels (6-10%) enhance CD4+ memory T cell activation compared to hyperoxic or hypoxic conditions.

  • 3

    Lck phosphorylation, crucial for TCR signaling, is altered in resting T cells exposed to varying oxygen levels.

  • 4

    Chronic hypoxia in inflammatory conditions may suppress CD4+ T cell function, impacting their role in diseases like rheumatoid arthritis.

  • 5

    Experimental designs must consider oxygen levels to accurately reflect T cell behavior in vivo and improve therapeutic strategies.
