Monoclonal antibodies are produced by immunizing animals with synthetic peptides corresponding to residues surrounding Leu310 of mouse HS1, His140 of human Akt3, Leu706 of human Stat2, a phospho-specific synthetic peptide corresponding to residues surrounding Tyr690 of human Stat2 protein and Ser473 of human Akt, and recombinant mouse ASC/TMS1 protein.
Distinct microglial activation states have been identified using RNA-seq data from a vast array of neurological disease and aging models. These activation states have been categorized into modules corresponding to proliferation, neurodegeneration, interferon-relation, LPS-relation, and many others (1). Previous work identifying markers of specific brain cell types using RNA-seq has shown HS1 and ASC/TMS1 to be useful and specific tools to study microglia (2). HS1 is a protein kinase substrate that is expressed only in tissues and cells of hematopoietic origin (3) and ASC/TMS1 has been found to be a critical component of inflammatory signaling where it associates with and activates caspase-1 in response to pro-inflammatory signals (4).
Stat2 is critical to the transcriptional responses induced by type I interferons, IFN-alpha/beta (5,6). In response to IFN-alpha/beta, Stat2 is activated by phosphorylation at site Tyr690 through associations with receptor-bound Jak kinases (7). Akt is a protein kinase that plays a critical role in controlling survival and apoptosis. Akt is activated by various growth and survival factors to function in a wortmannin-sensitive pathway involving PI3 kinase (8-10) and its activity is shown to be essential for up-regulation of key IFN inducible proteins (11). Akt is activated by phospholipid binding and activation loop phosphorylation at Thr308 by PDK1 (12) and by phosphorylation within the carboxy terminus at Ser473. The previously elusive PDK2 responsible for phosphorylation of Akt at Ser473 has been identified as mammalian target of rapamycin (mTOR) in a rapamycin-insensitive complex with rictor and Sin1 (13,14).
