The presence of red cells with reduced mean corpuscular volume (MCV) reflects reduced hemoglobin synthesis, which can have several causes. It can result from defects either in iron acquisition or availability, or in heme or globin synthesis. Experimental data in mouse ...

When these cells get activated i.e. come in contact with pathogens, they process them and move to lymph nodes to present the processed antigen. Thus these ...
