1. Neutrophils- They constitute the majority of the white blood cells( 50℅- 70%). In response to infections, the number of circulating leukocytes increases significantly. They are recruited at the site of infection to inflammatory molecules like chemokines generated by the innate cells which have engaged a pathogen. Neutrophils phagocytize bacteria effectively and secrete a range of proteins that have antimicrobial effects and also tissue remodeling potential .Neutrophils have a well-established role during fungal and extracellular bacterial infections where they promote bacterial clearance through phagocytosis. 2. Basophils/ Mast Cells- They contain large granules filled with basophilic proteins. They are relatively less in number but are very potent. In response to the binding of circulating antibodies, basophils release their content of granules (Histamine is one of the known proteins present in basophilic granules) Histamine increases blood vessel permeability and smooth vessel permeability. Mast cells too release cytoplasmic granule that has histamine and regulate inflammation. 3. Eosinophils- These are also motile phagocytic cells and play important role in defense against multicellular parasitic organisms. They form clusters around worms whose membranes are damaged by the activity of proteins released from eosinophilic granules. 4. Macrophages and dendritic cells - They play a primary role in activating T cells and also play an important role in regulating repair and regeneration. They are also referred to as inflammatory macrophages as play a dual role in clearing pathogens from tissue as well as antigen-presenting the cells that activate T cells They can kill ingested bacteria and secret inflammatory and cytotoxic mediators. Dendritic Cells perform the function of antigen capture at one location and antigen presentation on other 5. Natural Killer Cells- These cells are lymphoid cells. On their surface, they have a surface marker known as NK1.1. They are efficient cell killers attack a variety of abnormal cells including tumor cells. They differentiated between normal and cells to be killed by " Recognizing " the absence of MHC class 1 which is expressed by all normal cells .From the above explanation, we can match the cells with respective function in following order: 1.Basophils and Mast Cells - C Stimulates inflammation 2. Natural Killer Cells- A Kills diseased Human Cell 3. Eosinophils- B Targets primarily eukaryotic bacteria and viruses 4. Macrophages and dendritic cells- E Use phagocytosis and present antigen to adaptive cells 5 Neutrophils- D Target primarily extracellular bacteria
