Hemoglobin Variant A2 May Protect MS Patients Against Neural Injury
Multiple sclerosis seems to be less severe in people with higher levels of the minor adult hemoglobin variant A2 (HbA2) in their blood, according to a team of Turkish researchers. This could be due to this variant having a higher protective effect on the red blood cell membrane. The authors speculate that HbA2 could therefore be playing a role in reducing long-term neural injury in MS.
