Abstract:
Malignant peritoneal mesothelioma (MPeM) is a rare primary malignant tumor originating from peritoneal mesothelial cells. Insufficient specificity of the symptoms and their frequent reappearance following surgery make it challenging to diagnose, creating a need for more efficient treatment options. Natural killer cells (NK cells) are part of the innate immune system and are classified as lymphoid cells. Under the regulation of activating and inhibiting receptors, NK cells secrete various cytokines to exert cytotoxic effects and participate in antiforeign body, antiviral, and antitumor activities. This review provides a comprehensive summary of the specific alterations observed in NK cells following MPeM treatment, including changes in cell number, subpopulation distribution, active receptors, and cytotoxicity. In addition, we summarize the impact of various therapeutic interventions, such as chemotherapy, immunotherapy, and targeted therapy, on NK cell function post-MPeM treatment.
Insights
Malignant peritoneal mesothelioma (MPeM) treatment impacts natural killer (NK) cells. This review details changes in NK cell function and subpopulations after MPeM therapies, offering insights for improved treatment strategies.
Area of Science:
- Oncology
- Immunology
Background:
- Malignant peritoneal mesothelioma (MPeM) is a rare cancer with challenging diagnosis and treatment due to non-specific symptoms and recurrence.
- Natural killer (NK) cells, crucial components of the innate immune system, possess antitumor activities.
- Understanding NK cell behavior post-MPeM treatment is vital for developing effective therapeutic strategies.
Purpose of the Study:
- To comprehensively review alterations in NK cells following MPeM treatment.
- To summarize the impact of various therapies on NK cell number, subpopulations, receptor activity, and cytotoxicity.
- To consolidate current knowledge on NK cell modulation in the context of MPeM.
Main Methods:
- Literature review and synthesis of existing studies on MPeM and NK cell interactions.
- Analysis of data regarding NK cell dynamics (number, subpopulations, receptors, cytotoxicity) in MPeM patients undergoing treatment.
- Compilation of information on the effects of chemotherapy, immunotherapy, and targeted therapy on NK cells in MPeM.
Main Results:
- MPeM treatment leads to specific changes in NK cell count, distribution of subsets, expression of activating/inhibiting receptors, and cytotoxic function.
- Different therapeutic modalities (chemotherapy, immunotherapy, targeted therapy) exert varied effects on NK cell activity.
- These alterations highlight the complex interplay between MPeM and the host immune system, particularly NK cells.
Conclusions:
- NK cell function is significantly modulated by MPeM treatments.
- Further research into NK cell-based therapies and monitoring is warranted for optimizing MPeM management.
- Targeting NK cell responses could represent a promising avenue for future MPeM treatment strategies.
