About the Rhesus Monkey (or Rhesus Macaque)
The rhesus macaque is one of the most commonly utilized non-human primates in biomedical research. They are employed in numerous research areas, such as immunology, neuroscience, oncology, infectious disease, and toxicology due to their physiology.
Rhesus Macaque Monkey CD3 Pan T Cells
Rhesus CD3 pan T cells consist of both CD4 and CD8 T cells, and make up approximately 52-80% of PBMCs in a typical adult monkey. All T cells carry the CD3 protein marker and the T cell receptor (TCR), which recognizes foreign antigens presented by major histocompatibility complex molecules on antigen presenting cells to activate them.
T cells develop in the thymus to become mature CD4 or CD8 T cells and exit the thymus to reside and encounter foreign pathogens in lymphoid tissues.
When activated, CD4 T cells will become T helper subsets to secrete cytokines to boost either the humoral or cell-mediated immune response. In contrast, CD8 T cells, when stimulated, will become cytotoxic T cells that can lyse infected or transformed cells. Together, these two main subsets work to clear infections or diseased cells.
Pan T Cell Application Summary
Purified rhesus T cells are a good source of cells to study the biology of T cells and their role in the immune system. T cells are responsible for producing cytokines and performing cytotoxicity. Thus, pan T cells can be used for a variety of stimulation-dependent functional experiments to assess cytokine production, proliferation, and cytotoxicity.
With the current trend toward development of immuno-modulatory drugs, purified rhesus pan T cells are an ideal source of cells to test T cell response in the presence of therapeutic molecules. More importantly, rhesus T cells can be used to assess toxicity and safety characteristics of these biologics in the presence of T cell activation before first in-human trials. These cells are commonly employed in pre-clinical settings to ensure biologics are not eliciting unwanted functions, such as cytokine release and toxicity, specifically from T cells.
The negative isolation of pan T cells leaves them untouched without any antibody binding to cell surface markers that may influence function. This method leaves all cell surface proteins eligible to be bound to antibodies or other molecules for functional or population characterization studies.
In contrast, positive isolation of pan T cells may lead to internalization of the marker that was used to isolate the cells. In most cases, these markers are only used for identification purposes and may not have any effect on function, but it will depend on the organism and function. Therefore, cells isolated using this method may also be employed for functional or population characterization studies with the knowledge that the isolation marker may be internalized and not present.
Pan T Cell Purification
Collection of samples
Rhesus PBMCs were sourced from a responsible third party vendor that operate according to local regulations and laws.
Isolation of Rhesus CD3 Pan T cells
To enrich for rhesus CD3 pan T cells by the negative isolation method, PBMCs were incubated with antibodies against B cells, NK cells, dendritic cells, monocytes, granulocytes, and erythrocytes, and subsequently subjected to a magnet. Cells labeled with the antibodies bound to the magnet through the test tube wall, while unlabeled cells, the CD3 pan T cells, were decanted into a fresh tube to obtain the enriched population.
For the positive selection method, PBMCs were incubated in a test tube with antibodies against a pan T cell-specific marker and subsequently subjected to a magnet, similar to negative isolation. However, the cells that were decanted into the fresh test tube were the non-pan T cells, which can be used for other purposes, while the labeled pan T cells were left bound to the magnet through the test tube wall. The test tube was then removed from the magnet to release the purified pan T cells directly into the test tube.
Cryopreservation and storage
Purified CD3 pan T cells were cryopreserved carefully using iQ Biosciences’ cryopreservation protocol that ensures high viability (> 90%) after thawing.
Cells should be stored at < -120 °C once they are received, such as within a liquid nitrogen tank (vapor phase).
