The study found that IL-1β works by activating myeloid derived suppressor cells, which are pro-inflammatory and contribute to gastric inflammation.
A new study reveals that H. pylori bacteria can exploit stomach cells to protect themselves from the immune system, increasing the risk of stomach cancer. The bacteria's interaction with gastric cells triggers a receptor called Decay-accelerating factor (DAF), which reduces immune damage and promotes chronic inflammation.
A randomized controlled trial found that removing H. pylori bacteria from stomachs of post-operative stomach cancer patients can significantly reduce the risk of stomach cancer redeveloping. The study showed a two-thirds reduction in metachronous gastric cancer development between eradication and control groups.
Researchers at Rhode Island Hospital have identified two proteins, GKN1 and GKN2, which are produced by normal stomach cells. Patients with poor outcomes following surgery for stomach cancer had extremely low amounts of these proteins. The discovery may help physicians better determine and individualize therapy for stomach cancer.
Researchers at MIT have confirmed the long-suspected link between chronic inflammation and increased cancer risk. Chronic stomach inflammation damages DNA, which can lead to mutations that cause cancer. Individuals with poor DNA repair systems may be more susceptible to developing cancer associated with chronic inflammation.
