expresses expresses striatum neuron GABAergic interneuron striatal pthlh-expressing interneuron According to spatial transcriptomic data in the human striatum, pthlh-expressing interneurons are one of the most abundant population of interneurons in the striatum (Leonardo D. Garma, et al., 2024). PTHLH +/PVALB+ interneuron A GABAergic interneuron expressing PTHLH and PVALB that has its soma in a striatum. This GABAergic interneuron type presents a spatial expression gradient of PVALB in the mouse striatum. PTHLH/PVALB cell parathyroid hormone-related protein parvalbumin alpha
