Adoptive T-cell therapy for fungal infections in haematology patients

Area of Science:

• Immunology
• Mycology
• Transplantation

Background:

• Patients undergoing hematopoietic stem cell transplant and chemotherapy face prolonged immune deficiency, increasing susceptibility to invasive fungal infections.
• Despite advances in diagnostics and treatment, mortality from invasive mould infections remains high in allogeneic stem cell transplant recipients.
• Emerging drug-resistant and rare fungal strains present significant clinical challenges.

Purpose of the Study:

• To review the incidence and evolving patterns of invasive fungal diseases in immunocompromised individuals.
• To examine the role of T cells in fungal immunity and the potential of adoptive T cell therapy.
• To discuss methods for expanding fungus-specific T cells and considerations for their clinical application.

Main Methods:

• Review of current literature on invasive fungal diseases and T cell-based immunotherapy.
• Analysis of clinical evidence supporting T cell-mediated fungal immunity.
• Discussion of laboratory techniques for isolating and expanding fungus-specific T cells.

Main Results:

• Adoptive therapy with in vitro-expanded Th-1 type fungus-specific CD4 cells has demonstrated efficacy in preclinical (murine) and early clinical studies.
• Various methods for isolating and expanding fungus-specific T cells have been successfully developed.
• T cells play a crucial role in controlling fungal infections.

Conclusions:

• There is a critical need for novel strategies to manage invasive fungal infections in immunocompromised populations.
• Adoptive T cell therapy represents a promising immunotherapy for combating fungal infections.
• Further research and clinical studies are warranted to optimize T cell-based fungal immunotherapy.
