The UK Foreign Office has issued a travel advisory for Cape Verde, warning travelers about a recent spike in dengue fever cases on the islands of Santiago, Fogo, and Brava. The advisory emphasizes the need for preventive measures and highlights the limited medical facilities available on the islands.
Scientists have discovered a specific type of immune cell, called GD3 cells, that plays a crucial role in determining how itchy a person gets after an allergic reaction, such as a mosquito bite. These cells release a signaling molecule called interleukin 3 (IL-3), which activates sensory neurons in the skin, making them more likely to trigger an itch. The research, conducted in mice, offers potential new targets for treating chronic itch disorders.
