Primers used were: MCP-1, 5′-CCCACTCACCTGCTGCTACT-3′ (sense) and 5′-TCTGGACCCATTCCTTCTTG-3′(antisense); CCR2, 5′-GTACCCAAGAGCTTGATGAA-3′ (sense) and 5′-GTGTAATGGTGATCATCTTGT-3′(antisense). Gene expression for CCR2 was also assessed using semiquantitative RT-PCR.  Briefly, RNAs were treated with DNase I prior to reverse transcription.  Reverse transcription

was performed on 1 μg of RNA using random hexamers as primers.  Semiquantitative real time PCR was performed on cDNAs using TaqMan® expression assays (Life Technologies) specific for each target gene. All reactions were run on a 96-well, 7300 Real Time PCR System (Life Technologies). Expression of all target genes was normalized using HPRT as the control housekeeping gene. Data were compared in all cases between each treated-mice group with XAV-939 cell line its own Y-27632 cost control group. For statistical significance data were analyzed by means of a Student’s unpaired t test with p < 0.05 considered as significant.

MCP-1 expression in the thymi of T. cruzi infected mice is restricted to B cells and resident CD4+ and CD8+ thymocytes. WT mice were infected with 5 × 105 trypomastigotes (i.p.). On day 12–14 post infection, thymocytes were obtained and cultured for 4 h in the presence of Brefeldin A. MCP-1 expression was determined by intracellular staining in CD44hi and CD44lo CD4+ and CD8+ SP cells, B cells, DCs cells, and macrophages.
