The innate immunity adaptor SARM translocates to the nucleus to stabilize lamins and prevent DNA fragmentation in response to pro-apoptotic signaling.

Sterile alpha and armadillo-motif containing protein (SARM), a highly conserved and structurally unique member of the MyD88 family of Toll-like receptor adaptors, plays an important role in innate immunity signaling and apoptosis. Its exact mechanism of intracellular action remains unclear. Apoptosis is an ancient and ubiquitous process of programmed cell death that results in disruption of the nuclear lamina and, ultimately, dismantling of the nucleus.

Flow cytometric evaluation of adhesion of Streptococcus pyogenes to epithelial cells.

The precise roles of various surface molecules in the attachment of Streptococcus pyogenes to host epithelia are currently unclear. A flow cytometry assay that facilitates the analysis of the kinetics of S. pyogenes adhesion to epithelial cells was developed.
