Lymphoid cells show an adapted NK cell population in latent tuberculosis cases

In a study of NK cell repertoire and tuberculosis (TB), Garand and coworkers found a diversified population of NK cells in latently infected individuals versus active TB cases. NK cells from latently infected individuals exhibited a higher frequency of memory-type surface markers. The results indicate a primed NK cell population resulting from previous TB exposure, thus, bridging innate and adaptive immunity.

In this study,  Medonic M32 hematology system was used.
