- [Vogt2014lhx] “PV interneuron specification follows a hierarchical transcription factor cascade that progressively restricts cell fate from pan-MGE progenitor to mature PV identity. NKX2-1 sits atop this hierarchy, directly binding a conserved sequence in the *Lhx6* promoter to activate its transcription [Du2008nkx].

- [Denaxa2012maturation] “Downstream of LHX6, two critical effectors — SOX6 and SATB1 — act in concert to consolidate PV identity. SATB1 functions as a maturation-promoting factor in MGE-derived cortical interneurons; loss of SATB1 disrupts the normal maturation program of MGE-lineage interneurons, demonstrating its essential role in the developmental consolidation of interneuron identity downstream of LHX6 [Denaxa2012maturation].

- [Hu2017coup] “The divergence of PV and SST fates within the MGE is not governed by a single linear pathway. COUP-TF1 and COUP-TF2 (NR2F1/NR2F2) promote SST+ fate and repress PV+ fate, in part through direct regulation of *Sox6* expression [Hu2017coup].

- [Voss2022interneuron] “A striking paradox emerges from the temporal dissection of TF requirements. LHX6 is indispensable during embryonic development — its loss severely disrupts PV and SST interneuron specification [Vogt2014lhx], and *Lhx6* is necessary to rescue PV and SST interneuron phenotypes in *Nkx2-1*-null transplant experiments [Du2008nkx]. Yet postnatal removal of *Lhx6* does not affect PV interneuron number, morphology, or elec...”
