The present study demonstrated that octreotide therapy, administered at 50 μg/kg/day by intraperitoneal injection from day 10 to 17 post-infection, decreased mRNA levels of SSTR1 and SSTR2 on day 14 post-infection, although it increased mRNA levels of SSTR1, SSTR2 and SSTR3 on day 50 post-infection. This evidence concerns the gene SSTR1 and infection.
