Israeli researchers have identified a previously unknown type of immune cell, dubbed “ruptoblasts,” that plays a crucial role in defending the body against infection. The discovery, announced by Ben-Gurion University of the Negev, reveals these cells function by a unique mechanism described as an “eruption.” This process actively combats infections, offering a new understanding of the immune system’s response. Researchers observed that ruptoblasts rapidly deploy to infection sites. The finding could potentially lead to new therapeutic strategies for boosting immunity and treating infectious diseases. Further research is planned to fully understand the ruptoblast’s capabilities and potential applications.
