WebJan 17, 2024 · White blood cells, also known as leukocytes, are immune cells that circulate in the blood and lymphatic system. There are 5 main types: Neutrophils – main action against bacterial and fungal infections. Monocytes – main action against bacterial infections. Eosinophils – main action against parasitic infections. WebMast cell- and basophil-specific transcriptional profiling, at rest and after activation by innate and adaptive stimuli, may help to unravel the degree to which these cells differ and facilitate a clearer understanding of their biological functions and how these could be targeted by new therapies.
