T Cell Immunology

T cells play a pivotal role in combating infectious diseases

The immune system is a complex network of cells and proteins that defend the body against infection. Key cells like T cells, B cells, macrophages, dendritic cells and neutrophils work together to identify, eliminate, and neutralize pathogens. T cells can play an important role in the diagnosis and monitoring of infectious diseases.

T cells, or T lymphocytes, are important cells in the adaptive immune system, playing a central role in orchestrating almost all adaptive immune responses by1, 2:

  • Eliminating infected or cancerous cells
  • Mobilizing immune cells to mount robust immune responses
  • Developing a pathogen memory to prevent reinfection
  • Stimulating B cells to generate antibody responses

By utilizing an enzyme-linked immunospot (ELISPOT) assay, we can identify and analyze T cells responses to pathogens, allowing for the identification of T cells that are responsive to specific antigens.

T-SPOT technology

T cell immunology T-spot technology

 

We have over 20 years of experience in T cell immunology and accurately measuring T cell responses using our T-SPOT technology. By leveraging the ELISPOT methodology to perform an interferon-gamma release assay (IGRA), it offers a refined analysis of individual immune responses to specific antigens.

The technology includes 3 crucial steps:

  1. Cell isolation: Extract the desired cell population (PBMCs) from whole blood
  2. Cell washing: Enables removal of potential interfering substances from whole blood
  3. Cell counting: Ensures the required number of cells are used to produce reportable and accurate results regardless of individual patient cell counts

Through this innovative technology, we demonstrate our commitment to pushing the boundaries of healthcare and harnessing the power of the immune system to enhance diagnostic accuracy and improve patient outcomes.
