    DOCK8 is an atypical guanine nucleotide exchange factor that activates Rho family GTPases, crucial for immune cell function.

  • 2

    In T cells, DOCK8 supports migration, immunological synapse assembly, and long-term survival, enhancing antiviral defense.

  • 3

    DOCK8 fine-tunes BCR signaling in B cells, facilitating humoral immunity and immunological memory through metabolic reprogramming.

  • 4

    Deficiency in DOCK8 leads to severe immunodeficiency, characterized by increased susceptibility to infections and allergic diseases.

  • 5

    Future research should focus on elucidating DOCK8's multi-tiered signaling networks and developing targeted therapeutic strategies.
