T cells, also known as T lymphocytes, are an important component of the immune system. They are cells that have been specifically designed to combat infections that they have not yet encountered. Any research project may necessitate the requirement of T cell separation. They develop in the thymus before being released into the bloodstream as naive T cells. Naive T lymphocytes are unassigned T lymphocytes that are looking for an antigen-presenting cell (APC).
T Cell Activation
When a T cell comes into contact with a recognizable APC, the immature cell receives a signal to mature. BCR, TCR, and cytokine signals are the three types of signals. A cell will mature into an effector cell if it receives all three signals and it will be rendered ineffective if it only receives one of the signals (TCR or BCR).
Effector Cells
Depending on the APC encountered, a naive cell can develop into an effector T cell. Effector T cells have relatively short lifespans and carry out immune response functions. They have the ability to be cytotoxic, helper, or regulatory T cells.
Cytotoxic T Cells
The primary function of cytotoxic T cells, also known as CD8+ cells, is to kill toxic/target cells. When they are recognized, their purpose changes to the removal of virally infected cells, bacteria, and tumor fragments (such as cancer cells) via a process known as apoptosis. Apoptosis occurs when the internal organelles of a cell are destroyed, causing the cell to die from the inside out.
Helper T Cells
T helper cells, also known as CD4+ cells, are similar to cytotoxic cells but perform a broader range of functions. These cells are critical to cell immunity because they are required for the majority of adaptive immune responses. When exposed to antigens, T helper cells become activated and have the ability to differentiate into cell subtypes. Helper T cells multiply and secrete cytokines when activated, attracting macrophages and cytotoxic T cells to the infected site.
Regulatory T Cells
Once the threat has been eliminated, regulatory T cells are tasked with suppressing the autoimmune response. After helper T cells and cytotoxic T cells bind to a pathogen and collaborate to eliminate it from the body, they no longer serve a purpose. Regulatory T cells keep them from taking up space or attacking healthy cells until they die of apoptosis.
Memory T Cells
While these three types of effector cells handle the majority of the immune response, they are not the only T cell variations. Some T lymphocytes remain after a pathogen has been removed. These long-living lymphocytes are memory T cells that can respond to antigens when they are reintroduced.
These cells are formed following infection and are extremely important because they have the ability to multiply into large numbers of effector T cells when exposed to familiar antigens. Memory cells are distinct in that they remember pathogens and infectious cells faster than other cells, allowing them to fight bacteria and viruses more effectively. Vaccines can induce immunization in the body because of memory T cells.
Applications
Each of these T cell variants can aid in our understanding of diseases and our bodies’ responses to them. Adaptability is taught by naive T cells; effector cells provide treatment ideas, and memory is taught by memory cells. T cells help us create vaccines and medicines. T cells are an important component of medical research and could pave the way for many breakthroughs in the near future.
Try Pluriselect’s Cell Separation Products Today
If you’re looking for the most effective way to separate T cells from unwanted cell populations, pluriBead and pluriSpin technology provides an exceptionally gentle method for T cell enrichment that preserves the physiology and health of sensitive immune cells. While some cell separation methods can be rough and harmful to rare and delicate cell types, our cell separation technology works quickly and gently while preserving cell health and physiology.
Plurispin
The pluriSpin system is a new negative cell isolation technology directly from whole blood, buffy coat, or cord blood. Without the use of magnets or a column, this new method isolates viable, untouched, and highly purified cells in a single step. As a result, the cells of interest are less likely to be activated or damaged.
Key Features of PluriSpin
- One-step negative cell separation that is quick, simple, and inexpensive
- Isolate cells from whole blood, buffy coat, or cord blood using pluriSpin and the optimized protocol with standard density gradient centrifugation.
- PluriSpin does not necessitate any additional training or equipment, such as specialized instruments or magnets. You will only need a mixer, such as a whipping rolling mixer or our magnetic stirrer adapter (pluriPlix).
- Isolated cells are highly viable and functional, are flow cytometry compatible, and are not labeled with antibodies or magnetic beads.
- No columns, no magnets required
- Untouched cells for maximum viability
- Remove platelet contamination with PLT Depletion
- Independent of RBC concentration
PluriBead
It is a unique cell separation technology that does not rely on magnetic components. The steps are straightforward: the pluriBeads (containing bound target cells) are sieved through a strainer; the pluriBeads containing your target cells remain on top, while the unwanted cells pass through. After detaching, you have your target cells ready.
Key features of Pluribead
- Any sample material can be used: Buffy coat, whole blood, secretion/excretion material, PBMC, brain homogenate, spleen, liver, and so on.
- Isolate from mouse, rat, bovine, human, canine, sheep, and other species.
- Fast Isolation: Starting from 5 minutes
- Careful Isolation: A high yield of viable cells reduces the number of samples required. PluriBeads universal: For use with any secondary antibody produced in different species.
- Simultaneous Cell Isolation with pluriBead Cascade: At the same time, separate two different cell types from the same sample material.
- Isolation of Cells in Sequence: Isolate up to six distinct targets from a single sample.
- There are two different bead sizes to choose from: The first is S-pluriBead, which is ideal for a small number of targets in a large sample volume (e.g. CTC). Another is M-pluriBead, which is recommended for a wide range of targets in small materials (e.g. buffy coat).
- Suitable for a wide range of targets, including cell culture, proteins, viruses, whole blood, bacteria, and RNA / DNA.
