Editorial note on a Innate Immunity

Aniekan Jumbo*

Humans come into contact with potentially dangerous diseasecausing species or pathogens, such as bacteria or viruses, every day they live. Despite this, the majority of us are still able to act normally and live our lives without being sick all of the time. That's because a multilayered immune system is needed to keep the human body working smoothly. When a pathogen infiltrates a cell, cytoplasmic receptors detect the invasion and stimulate the immune response to prevent the pathogen from replicating. Another innate defence mechanism is the mobilisation of Natural Killer (NK) cells, which can identify virus-infected cells and destroy them right away, preventing rapid viral spread. Adaptive or acquired immunity is a supplemental type of immunity found in vertebrates. Unlike innate immunity, this form of defence has a memory. When an infection is replicated, the adaptive arm of the immune system allows for a faster and more systematic immune response. For any novel infection, the lack of immediate cooperation between innate and adaptive immunity for infection suppression is a huge advantage.
