Human skin acts as a protective barrier between the body and the external environment. Skin microbiome and intercellular lipids in the stratum corneum (SC) are essential for maintaining skin barrier function. However, the interplay between skin bacteria and the lipids is not fully understood.

Using the CRISPR/Cas9 approach for disruption of two out of three IPR genes in HEK-293 cells, we generated three monoclonal cell lines, IP3R1-HEK, IP3R2-HEK, and IP3R3-HEK, with the single functional isoform, IPR1, IPR2, and IPR3, respectively. All engineered cells responded to ACh with Ca transients in an "all-or-nothing" manner, suggesting that each IPR isotype was capable of mediating CICR.
