Aging Markers in Equine Red Blood Cells.
- Journal Article
Summary
This research investigates potential markers of aging in horse red blood cells by fractionating them according to density and assessing for changes in markers such as membrane loss, oxidation, and alterations in intracellular free Calcium levels. The study proposes that monitoring of these markers, along with changes in red blood cell indices, distribution width and creatine levels, may be useful in detecting regenerative erythropoiesis in horses.
About the Study
The primary objective of this research was to identify potential markers of red blood cell (RBC) aging in horses, which may eventually be used to detect regenerative erythropoiesis.
- The authors compared red blood cells fractioned into three different density groups – low (L), medium (M), and high (H), and analyzed these fractions for various aging markers.
- Erythropoiesis is the process of producing new red blood cells. Detection of this activity, particularly regenerative erythropoiesis (which kicks in when there is an increased demand for new red blood cells such as in the case of blood loss or anemia), has been challenging in horses due to the lack of traditional hematopoietic markers in their circulation.
The Findings
- Cells in the L and M fractions were heterogeneous and prone to swell in response to a hypo-osmotic challenge, suggesting these cells may be older and more susceptible to osmotic stress.
- The H fraction cells had less of a protein called ‘band 3’, which is important to red cell function, compared to L and M fractions. This suggests that these denser cells may be aged or damaged in some way.
- Cells in the H fraction were more oxidized, which is a common feature of aging or damaged cells. This was deduced by observing an increase in autofluorescence and thiol oxidation, which are markers for oxidized or damaged hemoglobin.
- The L fraction cells showed decreased free thiol content compared to M fraction cells, which is typically indicative of changes in the cellular redox state associated with aging. However, these lightest cells were absent of oxidized hemoglobin, highlighting their complex and diverse nature.
- The level of intracellular free Calcium varied prominently across all fractions, along with its distribution within the cells, suggesting that calcium levels may be a potential aging indicator.
Potential Markers and Further Research
Based on these observations, the authors proposed several potential markers for red cell aging and regenerative erythropoiesis in horses, including:
- Intraerythrocytic Calcium levels and its subcellular distribution
- Eosin-5-maleimide binding test for band 3 abundance
- Cellular autofluorescence
- Alterations in red blood cell indices, distribution width, and creatine levels
The study acknowledges the need for further investigations and validation to confirm the utility of these proposed markers for red blood cell aging in horses.
