Understanding T-Cytotoxic & T-Helper Lymphocytes

Hello everyone,

From my previous blog (Explaining Alopecia Areata & Autoimmune Disease), I talked briefly about Alopecia Areata and then proceed to the discussion of the Immune System.

I have touched on the microscopic presence of T-Cytotoxic and T-Helper lymphocytes excessively on the hair follicles of a skin biopsy taken from a patient with Alopecia Areata.

Before I go on further to explain why Alopecia Areata is recognized to be an autoimmune condition. Let us watch the videos below to understand the normal function of T-Cytotoxic and T-Helper lymphocytes in our body's immune system.


T-Cytotoxic (Lymphocytes)
*Note: Antigens are proteins that are able to produce an immune response (E.g. proteins of bacteria, viruses)

-function to eliminate antigens by releasing cytoxic properties/substances.

T-Helper (Lymphocytes)

-function to eliminate antigens by signalling other immune cells.

Thats all for today, I shall talk about Alopecia Areata as an Autoimmune Disease at a later date. (I shall continue our discussion in about a week from now)

At the end of this series of blog, if the people who read and learned about Alopecia areata still behaved rudely and even jeer at people suffering from Alopecia areata. I shall make an official declaration on this kind of people.

As for the rest, thank you very much for your support, patience and interest in Alopecia areata.
