The development of biomaterial-based therapeutics to induce immune tolerance holds great promise for the treatment of autoimmune diseases, allergy, and graft rejection in transplantation. Historical approaches to treat these immunological challenges have primarily relied on systemic delivery of broadly-acting immunosuppressive agents that confer undesirable, off-target effects. The evolution and expansion of biomaterial platforms has proven to be a powerful tool in engineering immunotherapeutics and enabled a great diversity of novel and targeted approaches in engineering immune tolerance, with the potential to eliminate side effects associated with systemic, non-specific immunosuppressive approaches. In this review, we summarize the technological advances within three broad biomaterials-based strategies to engineering immune tolerance: nonspecific tolerogenic agent delivery, antigen-specific tolerogenic therapy, and the emergent area of tolerogenic cell therapy.

Adult human skin contains nearly twice as many T cells as the peripheral blood, which include tissue-resident memory T cells. However, the precise mechanisms maintaining tissue-resident memory T cells in the healthy skin remain unclear. Using normal human skin samples, we find that Langerhans cells (LCs) contact T cells in the epidermis of the elderly.

Objective: Although the combination of atezolizumab and bevacizumab (A+B) shows promise for advanced hepatocellular carcinoma (HCC), its response rate is still inadequate. Previous studies indicate that the integration of FOLFOX-based hepatic arterial infusion chemotherapy (HAIC) with transarterial chemoembolization (TACE) is advantageous for the management of HCC. This meta-analysis aims to assess the safety and efficacy of the A+B+TACE or HAIC therapy protocol in patients with advanced HCC.

Background: The current standard of care for infantile-onset Pompe disease (IOPD), a severe form of acid α-glucosidase enzyme activity deficiency is: (1) detection by newborn screening, (2) early initiation of intravenous enzyme replacement therapy (ERT) using recombinant human acid alpha-glucosidase (rhGAA), with higher doses of rhGAA increasingly used to improve clinical outcomes, and (3) immune tolerization induction (ITI) using to prevent anti-rhGAA antibody formation, with methotrexate (MTX), rituximab, and IVIG used for patients who are cross-reactive immunologic material negative (CRIM-) and monotherapy with MTX used in patients who are cross-reactive immunologic material positive (CRIM+).
Objectives/methods: A pilot study evaluates a dose-intensive therapy (DIT) using high-dose ERT (40 mg/kg/week) and more frequent exposure to ERT (i.e.

Immunological tolerance is a fundamental arm of any functioning immune system. Not only does tolerance mitigate collateral damage from host immune responses, but in doing so permits a robust response sufficient to clear infection as necessary. Yet, despite occupying such a cornerstone, research aiming to unravel the intricacies of tolerance induction is mired by interchangeable and often misused terminologies, with markers and mechanistic pathways that beg the question of redundancy.
