Tumor Immunotherapy01:27

Tumor Immunotherapy

2.1K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Cytotoxic T Cells-mediated Immune Response

7.7K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

  • To highlight bioengineering strategies for modulating T cell responses.

Main Methods:

  • Review of current research on biomaterial interfaces for immunoengineering.
  • Analysis of key T cell activation parameters, including substrate mechanics and receptor organization.
  • Discussion of bioengineering approaches to manipulate these parameters.

Main Results:

  • Biomaterials can be engineered to actively control immune cell activation and behavior.
  • Mimicking natural APC-T cell interactions via artificial interfaces is crucial for T cell control.
  • Substrate mechanical properties and spatial receptor organization are key tunable parameters.

Conclusions:

  • Biomaterial interfaces offer a powerful platform for immunoengineering T cell responses.
  • Understanding and manipulating biomaterial-interface parameters can lead to novel therapeutic strategies.
