A step forward in the fight against bacterial infections
...Ghent researchers administered 10 times the lethal dose
of LPS to the mutant mice, without deadly consequences. This finding could not be attributed to an alteration in TLR4, but to a reduced production of type 1 interferons. To verify this, Mahieu and her colleagues administered these interferons prevent...
