A subsection of this database, the Human Blood Atlas, focuses on the expression levels of all human protein-coding genes in major blood immune cell populations. In addition, the proteins actively secreted to blood (the Human Secretome) are described. Each node in this network shows the number of genes that are active in a specific immune cell population—both the number of genes enriched (high relative abundance of the protein) in a single cell type (red) and the number of genes enriched in several related cell types (yellow). For details and list of genes, see www.proteinatlas.org/blood. Function of blood proteins The liquid portion of blood is called plasma. It contains a complex mixture of proteins including clotting factors, antibodies, hormones, and enzymes, as well as sugars and fat particles. The abundance of blood proteins varies considerably, with only 10 proteins making up more than 90% of the total protein mass. Albumin is the most abundant, while signaling proteins like cytokines and hormones appear at much lower concentrations. The Human Blood Atlas lists the functional role of all proteins predicted to be actively secreted into the blood (figure on right) as well as their concentrations as determined by mass spectrometry and/or immunoassays (www.proteinatlas.org/blood). Blood disease and immune activation Certain proteins are essential for activating immune cells upon infection and their dysfunction leads to infectious disease susceptibility. Other proteins play critical roles in regulating immunity. Proteins with such activating or inhibiting functions are interesting targets for drug development. Examples of pharmaceutical drugs include anti histamines that control allergic reactions and biopharmaceuticals used to lower the levels of cytokines in autoimmune diseases, such as multiple sclerosis (TNF-α) and psoriasis (IL-17). In addition, targeting proteins that limit immune responses—so called checkpoint inhibitors such as PD-L1 and CTLA4—can boost the efficacy of immune cells, leading to dramatic improvements in patients with certain blood cancers, as well as showing promise in the treatment of solid tumors.

Introduction to the Human Protein Atlas

Erythrocytes (red blood cells) are small non-nucleated cells that transport oxygen and represent the most numerous cell type in the blood.

Platelets circulate in the blood until they are activated by tissue damage, where they aid in blood clot formation.

Granulocytes are a category of white blood cells involved in defending against bacteria and parasites. They are characterized by the presence of granules in their cytoplasm that contain, e.g., defensins, lysozymes and histamines. Cell types include neutrophils (most common), eosinophils, and basophils.

Monocytes are the largest of the white blood cells and are involved in immune responses to bacteria, viruses, and fungi. They can differentiate into macrophages that can penetrate into tissues and perform defense functions.

Dendritic cells are regulators of immune responses. They engulf and present fragments of pathogens to T cells in lymph nodes, enabling the adaptive immune response.

Natural killer (NK) cells are involved in innate immunity and releasecytotoxic granules to fight tumors and cells infected by a virus.

B cells produce antibodies to fight infections as part of the adaptive immune response.

T cells regulate the adaptive immune response and consists of many different cell types.

The genes in human blood cells

Blood cells make up approximately 40% of the blood volume and originate from stem cells in the bone marrow, where they mature into erythrocytes (red blood cells), platelets, and a large number of white blood cell populations that circulate throughout the body.
