Description de la cible

Innate Lymphoid Cells (ILCs) contribute to the innate immune system through cell signaling and regulation of immune cells. ILCs lack functionally rearranged T-Cell Receptors (TCRs) or immunoglobulin genes.1 ILCs have been categorized into three subsets. Group 1 ILCs include Natural Killer cells (NK) and other cells that produce IFN-γ but are distinct from NK cells.1 Group 2 ILCs are classified by their capability to produce cytokines, especially IL-5 and IL-13. Group 2 ILCs are sometimes known by variable names such as innate helper type-2 cells or natural helper cells.1 Group 3 ILCs are classified by the expression of Rorγt which is also needed for their development. This classification includes Lymphoid Tissue inducer cells (LTi) in addition to adult Rorγt+ ILC cells. ILC3 cells are important for lymphoid tissue development, mucosal homeostasis, containment of commensal bacteria, inhibition of the pathology that causes inflammatory bowel disease, thymic regeneration, control of mucosal IgA production, and immune defense capabilities against bacterial and fungal infections. ILC3 cells are also an important source of IL-22 which aids in the protection of intestinal mucosa from pathogens.1 MNK-3 is a novel, prototypical ILC3 cell line model which expresses the key transcription factors, cytokine secretion, cytokine receptors, chemokine receptors, and adhesion molecules represented in ILC3 cells. The MNK parental cell line was generated from sorted NIH-Swiss mouse fetal day-15 NK1.1+ thymocytes which were later transfected with constructs encoding the SV40 large T antigen and human c-MYC. Parental MNK cells were sorted to be NK-receptor negative. Two sublines were developed from parental MNK and later designated MNK-1 and MNK-3. NKR- MNK parental cells were cultured in IL-7 and IL-15 and confirmed to be negative for CD94, NKG2D, DX5, and CD11b. These NKR- cells became the MNK-3 subline.1 MNK-3 cells display LTi-like activity in vitro when incubated with mesenchymal stromal cells. A low ICAM-1, high VCAM-1 OP9 variant cell line was co-cultured with MNK-3 cells which resulted in a significant increase in ICAM-1 expression. This is essentially used as a readout for LTi activity.1 MNK-3 cells were confirmed by ELISA to secrete IL-22 at a basal level in addition to increased IL-22 secretion when stimulated by IL-1β, IL-23, and IL-2. MNK-3 cells also serve as a model for a high number of applications presented by ILC3 functions such as IL-17A induction. MNK-3 cells are also easy to genetically modify which can aid in application function. Source Cell line generated from sorted NIH-Swiss mouse NK1.1+ thymocytes. Cells were infected with a Bcl-2 retroviral producer cell line and transfected with replication-deficient SV40 and human c-myc constructs by electroporation.References1.
