Microglia are resident macrophages that provide the first line of defense and immune surveillance of the central nervous system. MicroRNAs are regulatory molecules that play an important role in many physiological processes including activation and differentiation of macrophages. In this article, we describe the method for measurement of microRNAs in microglia.
Using a lipophilic 1,1'-Dioctadecy-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI) staining technique, Ambystoma mexicanum can undergo vascular perfusion to allow for easy visualization of the vasculature.
This protocol isolates high quality total RNA from fecal samples of animal and human subjects. A commercial miRNA isolation kit is used with significant adaption to isolate pure RNA with optimized quantity and quality. The RNA isolates are good for most downstream RNA assays such as sequencing, micro-array, and RT-PCR.
The present protocol describes the construction of custom-made microelectrode arrays to record local field potentials in vivo from multiple brain structures simultaneously.
