Published: September 2012

IL-15 is a member of the IL-2 family of cytokines, which play a fundamental role in innate and adaptive immune responses. IL-15 has pleiotropic immune-enhancing activities, as it stimulates NK, T and NKT cell proliferation, survival and effector functions. In view of these properties, IL-15 is regarded as a good candidate for cancer immunotherapy. This possibility is reinforced by its low toxicity and efficacy in preclinical tumor models. The use of IL-15 to boost the immune response in HIV infection has also been proposed, although further studies are required to establish potential risks and benefits. Clinical trials of IL-15 have been initiated in cancer patients and in HIV vaccination and will elucidate the potential of IL-15-based immunotherapy. The purpose of this review is to provide an update on the potential applications of IL-15 in cancer immunotherapy and HIV infection.

Interleukin-15 (IL-15) emerges as a promising immunotherapeutic candidate, but the therapeutic utility remains concern due to the unexpected systematic stress. Here, we propose that the mRNA lipid nanoparticle (mRNA-LNP) system can balance the issue through targeted delivery to increase IL-15 concentration in the tumor area and reduce leakage into the circulation. In the established Structure-driven TARgeting (STAR) platform, the LNP and LNP can effectively and selectively deliver optimized IL-15 superagonists mRNAs to local and lungs, respectively, in relevant tumor models.

Article Synopsis
  • γδ T-cells play a crucial role in immune surveillance following HLA-Haploidentical Stem Cell Transplantation (haplo-HSCT), especially in pediatric patients.
  • A study showed that a specific subset of Vδ2 T-cells is associated with better antiviral protection, as these cells were more prevalent in patients who did not experience viral reactivation.
  • The research highlights how Vδ2 T-cells can inhibit CMV replication and enhance the immune response, suggesting their potential use in immunotherapy post-transplantation to combat both infections and tumors.

Interleukin-15 (IL-15) promotes the survival of T lymphocytes and enhances the antitumour properties of chimeric antigen receptor (CAR) T cells in preclinical models of solid neoplasms in which CAR T cells have limited efficacy. Glypican-3 (GPC3) is expressed in a group of solid cancers, and here we report the evaluation in humans of the effects of IL-15 co-expression on GPC3-expressing CAR T cells (hereafter GPC3 CAR T cells). Cohort 1 patients ( NCT02905188 and NCT02932956 ) received GPC3 CAR T cells, which were safe but produced no objective antitumour responses and reached peak expansion at 2 weeks.

CD2 expressing innate lymphoid and T cells are critical effectors of immunopathogenesis in hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic, debilitating inflammatory skin disease with a poorly understood immunopathogenesis. Here, we report that HS lesional skin is characterized by the expansion of innate lymphocytes and T cells expressing CD2, an essential activation receptor and adhesion molecule. Lymphocytes expressing elevated CD2 predominated with unique spatial distribution throughout the epidermis and hypodermis in the HS lesion.

Gamma delta (γδ) T cells are defined by their unique ability to recognize a limited repertoire of non-peptide, non-MHC-associated antigens on transformed and pathogen-infected cells. In addition to their lack of alloreactivity, γδ T cells exhibit properties distinct from other lymphocyte subsets, prompting significant interest in their development as an off-the-shelf cellular immunotherapeutic. However, their low abundance in circulation, heterogeneity, limited methods for expansion, and under-developed methodologies for genetic modification have hindered basic study and clinical application of γδ T cells.
