Breakthrough Portends Cure For the Common Cold

breadboy21 writes with this excerpt from the Independent: "Scientists have been able to show for the first time that the body's immune defenses can destroy the common cold virus after it has actually invaded the inner sanctum of a human cell, a feat that was believed until now to be impossible. The discovery opens the door to the development of a new class of antiviral drugs that work by enhancing this natural virus-killing machinery of the cell. Scientists believe the first clinical trials of new drugs based on the findings could begin within two to five years."

I wonder however how many flu symptoms are the effect of your body's defenses, and whether any of them will be worsened by such a drug

The cytokine storm that causes fatalities with some influenza variants is due (roughly speaking) to the body breaking down the virus too quickly, swamping its ability to dispose of the byproducts. This looks like it would cause your body to break down the virus faster, which could be problematic.

completely wrong way to think about colds

i just read this last month

the common cold is an immune system overreaction. the virus does not cause the cold, our own bodies overreact to the cold, and that causes ALL symptoms. which explains why cold medicines work: they modulate the immune response, they don't actually fight the virus

But, as medical science has realized over the past few decades, the most prevalent cold viruses in fact do little direct harm to our cells. In one experiment in 1984, researchers at the University of Copenhagen performed biopsies on nasal tissue taken from people suffering severe colds, then did the same after the subjects had recovered. To the scientists’ surprise, none of the samples showed any sign of damage to the nasal tissue. Further vindicating the viruses themselves was another study around the same time showing that rhinoviruses infect only a small number of cells lining the nasal passages.

so the virus comes in, borrows some cellular machinery for a few days, makes a few copies, and then leaves. our body's response is to call out the entirety of the navy, the marines, the army, the air force, the cavalry, mortar batteries, drone predators, and tactical nuclear strikes. for a crime which amounts to a homeless guy squatting in an unused home for a day or two
