We previously reported that mutants of dSeipin, the Drosophila homolog of human lipodystrophy gene Seipin which is important for fat storage and lipid droplet size [26], [27], exhibit ectopic lipid droplets in salivary glands, which can be stained by the neutral lipid dyes Nile red or Bodipy [28]. The gene discussed is BSCL2; the disease is lipodystrophy.
