DOCK8 regulates signal transduction events to control immunity

Abstract

Genetic mutations in the gene encoding DOCK8 cause an autosomal recessive form of hyper immunoglobulin E syndrome (AR-HIES), referred to as DOCK8 deficiency. DOCK8 deficiency in humans results in the onset of combined immunodeficiency disease (CID), clinically associated with chronic infections with diverse microbial pathogens, and a predisposition to malignancy. It is now becoming clear that DOCK8 regulates the function of diverse immune cell sub-types, particularly lymphocytes, to drive both innate and adaptive immune responses. Early studies demonstrated that DOCK8 is required for lymphocyte survival, migration and immune synapse formation, which translates to poor pathogen control in the absence of DOCK8. However, more recent advances have pointed to a crucial role for DOCK8 in regulating the signal transduction events that control transcriptional activity, cytokine production and functional polarization of immune cells. Here, we summarize recent advances in our understanding of DOCK8 function, paying particular attention to an emerging role as a signaling intermediate to promote immune responses to diverse external stimuli.

  • Patients with large deletions in the DOCK8 gene have increased susceptibility to pathogenic infections and exhibit allergic diseases.

    “In line with this, patients with large deletions in the DOCK8 gene experience increased susceptibility to pathogenic infections yet also exhibit allergic diseases, leading to great interest surrounding DOCK8 in the field of immunology, which has recently been reviewed in great detail (50, 115, 116).”

    From RHO to the DOCK for GDP disembarking: Structural insights into the DOCK GTPase nucleotide exchange factors (2021) · cites this paper as [116]

    The Introduction and Table 1 report that patients with DOCK8 deficiency have recurrent infections, eczema, and food allergy. The paper describes loss-of-function mutations generally, but does not establish that these manifestations occur specifically in patients with large DOCK8 deletions. (LLM, conf=0.85)

  • Mutations in the DOCK8 gene are associated with autism disorders.

    “Mutations in the DOCK8 gene have also been associated with autism disorders (116).”

    From RHO to the DOCK for GDP disembarking: Structural insights into the DOCK GTPase nucleotide exchange factors (2021) · cites this paper as [116]

    The Introduction links DOCK8 mutations to combined immunodeficiency, and the Conclusion discusses their effects on immune function. Neither passage addresses autism; searches for autism and related neurodevelopmental terms found no supporting passage in our copy. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
