Table 2 A detailed summary depicting the modifiable risk factors and their associated findings

From: Scavenger Receptor Class B type 1 (SR-B1) and the modifiable risk factors of stroke

SR-B1 Modifiable risk factors Findings References
Positive factors Diet - Mediterranean diet increases SR-B1 expression
- SR-B1 has an important role in the uptake of lipid-soluble vitamins, which have been associated with lower risk of stroke
- Chronic moderate alcohol accelerated cholesterol clearance via SR-B1-mediated reverse cholesterol transport
Nakamura et al. [52], Rimm et al. [53], Farras et al. [54], Han et al. [55]
Li et al. [56]
  Exercise - Increases SR-B1 expression Wei et al. [57]
Negative factors Smoking - Smoking decreases SR-B1 expression of keratinocytes and possibly type II pneumocytes Kolleck et al. [36], Sticozzi et al. [58]
  Diabetes - Increases SR-B1 expression
- SR-B1-knockout hyperglycemic mice had an increased incidence of coronary artery atherothrombosis, myocardial infarction, and early death
Hayashi et al. [59], Gonzalez et al. [60]
  Obesity - Obesity-induced upregulation of miR-24 could function as a feedback regulator of SR-B1 Wang et al. [61]
  Hypercholesterolemia/atherosclerosis - SR-B1 primarily functions in an atheroprotective capacity, when expressed in monocytes and macrophages Kozarsky et al. [62], Zhang et al. [63], Van Eck et al. [64], Galle-Treger et al. [40]
  Coronary heart disease
- SR-B1 deficiency leads to increased risk of CHD. Zanoni et al. [65]
  Hypertension - Lack of direct studies investigating SR-B1 expression in hypertension
- Indirect effects may be possible, as a lack of SR-B1 led to impairment of nitric oxide, a potent vasodilator
Pearson et al. [66], Hermann et al. [67]
  Sickle cell - No direct studies involving SR-B1 expression and sickle cell conditions
- Indirect involvement is possible, as lipid dysregulation partially determines severity of sickle cell
- SR-B1 is reported to facilitate cell-entry of malaria
