infections, and chronic inflammatory responses pose a permanent threat to our lungs. To date, the regenerative mechanisms leading to healing oflung injuryremain incompletely understood. Since few to no causal therapies are in place for most lung diseases,...
When we bought our condo, the marble countertops in the bathrooms were already badly damaged by inappropriate cleansers. In one bathroom, there were drip marks and the imprint of a spritzer-bottle from something acidic (acid dissolves marble), and in the other, the area near the sink was co...
Heart failure can be triggered by heart attacks and other conditions that damage theheart tissue. Doctors currently have no way to repair this damage because the body stops making cardiomyocytes shortly after birth. Saucerman and his team are eager to find drugs that can restart that natural produ...
Although DPP4 inhibitors are often used as medications for type 2 diabetes to control blood sugar, the researchers found that the inhibitors promoted production of AEC2 in mice with damaged lungs. However, the dose required when using existing inhibitors for lung repair would be too high and unsa...
Lungs become healthier after about one month, with less coughing. After ten years, the chances of developing fatal lung cancer go down by 50% probably because the body's ability to repair damage is once again restored.T here's no point pretending this is all easy to achieve. Quitting can...
A day after ceasing, heart attack risk begins to decrease as blood pressure and heart races 9 . Lungs become healthier after about one month, with less coughing. After ten years, the chances of developing fatal lung cancer go down by 50% probably because the body's ability to repair ...
Cells have a mechanism that is able to repair damaged DNA. If a cell detects that its DNA is damaged while it is dividing, it will self-destruct. Quickly multiplying cells have less time for the repair mechanism to detect and fix DNA errors before they divide, so they are more likely to...
The RBCs carry oxygen from the lungs; the WBCs help to fight infection; and platelets are parts of cells that the body uses for clotting. All blood cells are produced in the bone marrow. As children, most of our bones produce blood. As we age this gradually diminishes to just the ...
Let's look at how stem cells might be used to treat heart failure. Ideally, to treat a failing heart, scientists could stimulate stem cells to differentiate into heart cells and inject them into the patient's damaged heart. There, the new heart cells could grow and repair the damaged tissu...
There they can phagocytize bacteria (up to 100 in their lifetime) throughout the body. These cells also destroy old, damaged and dead cells in the body. Macrophages are found in the liver, spleen, lungs, lymph nodes, skin and intestine. The system of macrophages scattered throughout the ...
