Assays to examine lymphocyte invasion

Area of Science:

• Immunology
• Oncology
• Cell Biology

Background:

• Immune cell migration is vital for fighting infections, autoimmunity, and cancer.
• Effective cancer immunotherapy, particularly for solid tumors, relies on immune cell infiltration into the tumor microenvironment (TME).
• Current limitations in understanding immune cell invasion hinder the efficacy of cancer treatments.

Purpose of the Study:

• To present novel 2D and 3D in vitro methods for studying immune cell migration and invasion.
• To provide tools for better recapitulating the tumor microenvironment (TME) for human immune cell invasion studies.
• To advance research on immune cell infiltration barriers in cancer immunotherapy.

Main Methods:

• Development and adaptation of 2D and 3D in vitro models.
• Techniques designed to assess the migratory and invasive capabilities of immune cells.
• Focus on T cells and Natural Killer (NK) cells relevant to cancer immunotherapy.

Main Results:

• Established adaptable 2D and 3D methods for evaluating immune cell invasion.
• Provided a framework for studying immune cell behavior within a simulated TME.
• Demonstrated techniques applicable to understanding immunotherapy challenges.

Conclusions:

• The described 2D and 3D methods are valuable for investigating immune cell invasion.
• These techniques can aid in developing more effective cancer immunotherapies.
• Further research into immune cell migration is essential for advancing cancer treatment.
