Summary
Red blood cell (RBC) transfusions aim to improve oxygen delivery. However, storage alters RBCs, impairing oxygen transport and immune function, a phenomenon known as the "storage lesion."
Area of Science:
- Biomedical Science
- Hematology
- Transfusion Medicine
Background:
- Red blood cell (RBC) transfusions are critical for oxygen delivery.
- RBC processing and storage induce detrimental changes, termed the 'storage lesion.'
- The storage lesion impacts RBC oxygen transport, immune modulation, and coagulation.
Purpose of the Study:
- To review key features of the RBC storage lesion.
- To highlight the newly understood role of RBCs in regulating blood flow and oxygen consumption.
- To discuss how storage impairs RBC signaling functions and transfusion efficacy.
Main Methods:
- Review of existing literature on RBC storage lesion.
- Analysis of biophysical and physiological changes in stored RBCs.
- Discussion of emerging research on RBCs' role in vascular signaling.
Main Results:
- Storage increases RBC oxygen affinity due to depleted 2,3-BPG and ATP.
- Stored RBCs exhibit altered immune and coagulation properties.
- RBCs regulate vasoactive mediator bioavailability, a function disrupted by storage.
Conclusions:
- The storage lesion encompasses multifaceted RBC alterations affecting transfusion efficacy.
- Understanding the storage lesion is crucial for optimizing transfusion strategies.
- Further research into RBC signaling functions is needed to mitigate storage-induced impairments.

Factors Affecting Erythropoiesis
The cardiovascular system regulates the number of erythrocytes in the bloodstream to ensure optimal oxygen transport. It also prevents over-proliferation of these cells, which helps to maintain blood viscosity and flow rate.
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.

Lifecycle of Erythrocytes
Erythrocytes, also known as red blood cells, constantly move through blood capillaries. As a result, they damage their plasma membrane due to the continuous friction. Typically, after 100 to 120 days, erythrocytes become rigid and fragile as they wear out. As they pass through small vessels in the spleen and liver, they can get trapped and break apart into fragments.
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups.

Erythropoiesis
Red blood cells (RBCs) transport oxygen to all body tissues. These cells survive only for 120 days and then need to be replenished. Erythropoiesis is the process of RBC production. In healthy individuals, erythropoiesis ensures all tissues are amply supplied with oxygen. In addition, blood loss due to injury leads to a drop in the physiological oxygen level that will cause erythropoiesis. Any defect in erythropoiesis leads to several physiological disorders, including thalassemia, anemia, and...
Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Redox Reactions
Redox reactions are vital biochemical processes that underpin energy metabolism in cells. These reactions involve the transfer of electrons between molecules, occurring in tandem as oxidation and reduction. Oxidation refers to the loss of electrons, while reduction denotes their gain. This coupling ensures the seamless flow of electrons through metabolic pathways. For example, in bacterial metabolism, glucose undergoes oxidation to carbon dioxide, while oxygen is simultaneously reduced to...
Structure and Function of Erythrocytes
There are between 4.2 and 6 million erythrocytes, also known as red blood cells, in every microliter of blood. These cells are small, flattened biconcave discs with centers that are depressed.
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...
