Immunopharmacology Comments
HPK1 (MAP4K1) is highly expressed in hematopoietic cell subsets. It acts as a critical negative regulator in the activation of T cells and dendritic cells [6,14].
HPK1 inhibits T cell receptor (TCR) signaling via a mechanism that induces phosphorylation and ubiquitination of SLP-76 and it inhibits B cell receptor signaling by inducing phosphorylation and ubiquitination of BLNK [17].
Small molecule HPK1 inhibitors are predicted to induce immune responses in the tumour microenvironment [9], and are subsequently being investigated for immuno-oncology potential [10-11]. For example, Nimbus Therapeutics (in partnership with Celgene) have a declared HPK1 program in their development pipeline. Other pharmaceutical companies hold patents which claim HPK1 inhibitors [2-3,19].

Physiological Consequences of Altering Gene Expression Click here for help
Mice with hpk1 knock-out show enhanced T cell activation, increased cytokine production, and increased antibody production after KLH immunization. These findings confirm that hpk1 is a negative regulator of T cell receptor signalling and T cell-mediated immune responses.

General Comments
Hematopoietic progenitor kinase 1 (HPK1) regulates stress responses, proliferation, and apoptosis in hematopoietic cells. HPK1 has been identified as a novel target for cancer immunotherapy, whose inhibition may activate anti-tumour activity of both dendritic cells and T cells [11]. In contrast, a specific role of HPK1 as a novel tumor suppressor has been suggested by studies in pancreatic cancer [15].
