"Researchers have discovered a mechanism by which the body's immune reaction to viruses like influenza and HIV may cause learning and memory problems. This is the finding of a study led by researchers from NYU Langone Medical Center and published online May 15 in Nature Medicine. Evidence in mice suggests that the entry of a virus anywhere in the bloodstream turns on "first responder" immune cells called CX3CR1highLY6Clow monocytes, which then release the inflammatory signaling protein TNF-α. According to the authors of the study, TNF-α then travels to the brain where it blocks the formation of nerve cell connections needed to turn sensory information into memories. Although immune system activation by viruses has long been linked to cognitive problems, the underlying mechanisms have been poorly understood. In the new report."

u mean virus good for memory? diz researchers won't kill me.
cholesterol was the issue at the start of this month.. how it was bad but now good for d body. we learn from contradictory researches

This is simple comprehension/summary issue na oga. The opening and closing sentences of this report summarizes it all that viruses cause "memory and learning problems", which is already an established fact from previous researches. The only addition this research is making is explaining the mechanism through which that happens, which previous works did not talk about. Where in this report did you see that they're good for the memory instead? This report is just too short for one to find it difficult to comprehend.
