Cellular players of innate immunity, their sub-types and functions.

Leukocyte	Sub-Type	Function	Reference
1. Granulocytes/polymorphic nuclear cells (PMNs)	Neutrophils	Scavenger of invading pathogens	[69]
	Basophils	Release of inflammatory and anticoagulant mediators
	Eosinophils	Production of angiogenic and profibrogenic factors
2. Monocytes/mononuclear cells	Monocytes/macrophage	Phagocytosis	[70]
3. Lymphocytes	T cells	Orchestration of adaptive immunity	[71]
	B cells	Humoral immunity through antibody secretion
	Natural killer cells	Removal of tumor and virus-infected cells
