Scientists Discovered Four New Types Of Blood Cells

Scientists have identified new classes of cells in the human immune system.


Blood contains many types of cells, including many immune system components. Now, scientists have discovered new types of blood cells in the human immune system.

The newly discovered cell types are types of white blood cells called dendritic cells and monocytes. In total, scientists identified two new dendritic cell subtypes and two monocyte subtypes. They have also discovered a new dendritic cell progenitor.

Previously scientists used to discover the new type of blood cells by analyzing the marker proteins that they express on their surface. In this study, scientists used a single-cell genomics technique to analyze gene expression patterns in individual human blood cells. This new technique frequently overlooks hard-to-identify or rare types of blood cells. In addition, it is much more powerful and can reveal previously unrecognized and rare cell types that would be otherwise difficult to find.

Dr. Divya Shah from Wellcome Trust said, “Two important white blood cell types in our bodies help defend us from infection – dendritic cells and monocytes.”

“In this study, scientists have used cutting-edge technologies to find that there are much more types of cells than we originally thought.”

“The next step is to find out what each of these cell types does in our immune system, both when we’re healthy and during disease.”

This is the type of discovery that the Human Cell Atlas will produce in the future.
