Leukocytes

Leukocytes encompass a collection of cells that drives both innate and adaptive immunity.¹ They are found in blood, tissues, and organs, where they play a pivotal role in host defense through phagocytosis, pathogen elimination, inflammation mediation, and antigen processing and presentation.^1,2

All leukocytes develop from hematopoietic stem cells in the bone marrow and mature into either granulocytes – including basophils, neutrophils, and eosinophils – or agranulocytes, comprising monocytes and lymphocytes, that can further differentiate into specific cells.^1,2
