Question

Select the answer that correctly describes how Interferon beta 1a works to slow the progression of multiple sclerosis.

1 pt Interferon beta 1a acts directly on the neuron to attract more oligodendrocytes to produce more myelin.

Interferon beta 1a helps to regulate the immune system, preventing autoimmune attacks on the myelin.

Interferon beta 1a creates a protective sheath over the neuron, preventing the myelin sheath from being destroyed.

Interferon beta 1a stimulates Schwann cells to produce myelin in the central nervous system.

Interferon beta 1a is a neural stimulant, creating an environment where neurons can divide rapidly to replace those that are damaged.

Answer 1

Multiple sclerosis is an autoimmune disease where the immune system of their own body attacks the nerve sheath myelin that is healthier. This can be treated by giving the interferon beta 1a a immunomodulator drug which slows down the disease progression. This drug regulate the immune system and that will the prevent the autoimmune attack of the myelin so the disease progression is slower. The answer is Interferon beta 1a helps to regulate the immune system, preventing the autoimmune attacks on the myelin.

The interferon beta 1a doesn't produce any myelin by attracting oligodendrocytes so it's not suitable answer.

Interferon beta 1a will not create any protective sheath that covers myelin and protect the myelin so it's not suitable answer.

Interferon beta 1a do not stimulate Schwann cells for the myelin production so it's not suitable answer.

Interferon beta 1a is immunomodulator not an neuro stimulant so it's not suitable answer.
