Genetic Factors
Studies have shown that genetic factors play a role in the increased frequency of MS in the relatives of MS patients. However, identification of the genes that are involved has not been accomplished due to the small sample size. Generally, genes involved in the immune system are over-expressed and they implicate T-helper cell differentiation. T-helper cells are involved in the activation of T-cells which are responsible for entering the central nervous system and initiating demyelination processes.

Famous quotes containing the words genetic and/or factors:
“We cannot think of a legitimate argument why ... whites and blacks need be affected by the knowledge that an aggregate difference in measured intelligence is genetic instead of environmental.... Given a chance, each clan ... will encounter the world with confidence in its own worth and, most importantly, will be unconcerned about comparing its accomplishments line-by-line with those of any other clan. This is wise ethnocentricism.”
—Richard Herrnstein (1930–1994)
“Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.”
—Selma H. Fraiberg (20th century)
