i think it's called antigen
In dengue fever, white blood cells can decrease because the virus directly targets and destroys them. Additionally, the viral infection can trigger the immune system to release certain chemicals that can suppress the production of white blood cells. This decrease in white blood cells can make the body more vulnerable to infections.
red blood cells carry oxygen white blood cells attacks virus
white blood cells. red blood cells dont have nuclei so they cant do much
White blood cells can recognize viruses by their surface proteins, known as antigens. When a virus enters the body, white blood cells can lock onto these antigens to launch an immune response and target the virus for destruction.

1,White blood cells are one of the four main parts of blood. The other parts are the red blood cells, platelets, and plasma. There are different kinds of white blood cells, but they all have an important job. Do you know what that job is? White blood cells defend the body from infection and disease.2,Some white blood cells go to the places in your body where you have a cut. They attack any bacteria that enter your blood to stop them from spreading throughout your body.3,Some bacteria and viruses that enter your body carry chemicals called antigens. Your white blood cells make their own chemicals called antibodies, which will attach themselves to these antigens so that the poisons from the bacteria or viruses become harmless. Do you know how amazing these cells are? Well, the antibodies that your white blood cells produce only attack the antigen for which it was made. For example, an antibody for the chicken pox virus will only attack the chicken pox virus, not the measles virus. Even more amazing is that the white blood cells in your body remember how to make the antibody in case the germ ever enters your body again!Posted: By Nabeel pervez
White blood cells, specifically neutrophils and macrophages, produce a variety of chemicals such as cytokines, chemokines, and reactive oxygen species. These chemicals help regulate the immune response, attract other immune cells to the site of infection, and destroy invading pathogens.
Inflammatory chemicals are used to promote the release of white blood cells during an immune response. These white blood cells are released from the bone marrow.
Red blood cells carry oxygen throughout the body. White blood cells fight infections and help you from getting sick again by the same virus.
white blood cells fight infections
The cells you are referring to are called natural killer (NK) cells. NK cells are a type of white blood cell that plays a crucial role in the immune system by identifying and eliminating cancerous cells and virus-infected cells in the body. They are part of the body's innate immune response.
White blood cells are our way of fighting infection. When we become infected with say the Flu Virus, our immune system manages to identify the virus cells and it then produces more white cells to destroy the viruses. If we have a low white cell count, then our abillity to fight infections is diminished or reduced. Hope this helps.
