PROBLEM: Question: Does alirocumab , a Therapeutic Human Antibody to PCSK9 , Affect CD81 Levels or Hepatitis C Virus Entry and Replication into Hepatocytes?
Answer: These results suggest that inhibition of PCSK9 with alirocumab has no effect on CD81 and does not result in increased susceptibility to HCV entry.

SOLUTION: no

PROBLEM: Question: Does weight loss induced by bariatric surgery restore adipose tissue PNPLA3 expression?
Answer: Weight loss induced by LAGB restored adipose tissue PNPLA3 expression which is suppressed by TNF. Further studies will be required to determine the functional impact of PNPLA3 and its related genetic variation on adipose tissue inflammation and NAFLD.

SOLUTION:
yes
