SLAMF1 and tuberculosis: Actually, when we measured and compared the proliferation index and the SLAM expression on five days Mtb-Ag stimulated PBMC from HD carrying the different rs2275913 variants (data not shown), we observed that both parameters are statistically increased in PBMC from AA HD in comparison with GG HD, reinforcing the idea that AA individuals display a stronger cellular immunity against Mtb. Taking together, all these results indicate that the AA genotype of the rs2275913 SNP would be a biomarker of resistance to tuberculosis disease in the Argentinean population.
