What are Jurkat Cells used for in cell biology studies?
Jurkat cells are used most significantly to study T-cell Leukaemia, HIV and certain cancers. Jurkat and their derivative cell strains are immortal human T lymphocytes. They are possibly the best-known T-cell line making them a significant cell line. However, in recent years some caution has been advised when using this cell line in modelling typical T-cell function since a number of mutations have been identified. Nevertheless, it is a highly valuable cell line for these, and many other studies.
Most notably this cell line has been very useful for study of HIV, the causative virus of AIDS. Jurkat cells are susceptible to HIV infection since they have the CD4 T-cell receptor (TCR) that is required for HIV attachment and infection of this retrovirus. This makes Jurkat cells a good model to study some (but not all) of the complexities that are seen in HIV infections. Jurkat cell lines can also be used in screening of different antiretroviral treatment strategies. Antiviral agents can be toxic to the host cells meaning that pre-clinical screening of candidates is very important. One of the aspects of HIV that makes it so difficult to eliminate is that the provirus can remain at a low level in a latent reservoir, perhaps in as little as 1 in a million cells. This is enough for the virus to reappear 10 years later for example, if antiviral treatment had ended. It is complexities like this that can occur within clinical cases that can be difficult, if not impossible to replicate in cell line models.
