Answer:

Option A

Explanation:

New scientific investigation about universe always comes up with new theories. This happens because of two reasons -  

a) The exact knowledge of universal phenomenon is not known which lead to continuous investigation and hence new laws come up every time when a study or research is done

b) Also some scientist believes that universe is continuously expanding and changing due to which our previous theories no longer fit the current observations.  

Hence, option A is correct

improved intravitreal aav-mediated inner retinalgene transduction after surgical internal limitingmembrane peeling in cynomolgus
coldgirl [10]

Because it is easily accessible and has a mild immune response, the retina makes a good target for gene therapy.

  • In a mouse model, the inner retina was highly effectively transduced by an intravitreally injected adeno-associated virus (AAV) vector.
  • The vitreous and internal limiting membrane (ILM) operated as obstacles to transduction in large animals, reducing the efficacy of retinal transduction.
  • Before administering AAV vectors, we performed vitrectomy (VIT) and ILM peeling on cynomolgus monkeys to get around these obstacles.
  • The findings suggest that surgical ILM peeling prior to AAV vector delivery would be beneficial for retinal disease treatment and safe for effective transduction of the nonhuman primate retina.
