HIV destroys a particular variety of white blood cells that are essential for destroying disease-causing germs. There are several varieties of white blood cells in the body. Of these, lymphocytes form about twenty-five per cent of the total white blood cell count. They normally increase in number in response to any infection. There are two types of lymphocytes: (а) В cells and (b) T cells. When the В cells come in contact with a disease-causing agent such as bacteria or virus, they secrete large volumes of antibodies — chemical substances that can destroy the disease-causing germs. The main functions of В cells are to search, identify and then bind with the disease-causing germs.
The T cells are lymphocytes that have travelled through a small gland called the thymus gland, which is situated in the middle and upper part of the bony cage of the chest. When a disease-causing germ enters the body, the T cells produce several new copies of itself. Each T cell contains chemical substances that can destroy the specific disease- causing germs. T cells are also called "killer cells" because of their two main actions, which are (a) they secrete chemical substances necessary for destroying the disease-causing germs and (b) they help the В cells in destroying the agents.

Ronnie Shaw received his Bachelors degree in American Studies from the
University of California, Berkeley in the fall of 2003. In conjunction with research on
West African dance, his passion as an avid dancer and academic, he was compelled to study
abroad at the University of Ghana in West Africa, this changed his life. After living in Ghana
his commitment to creating progress in Africa was solidified: People often refer to Africa
as a place of absolute hopelessness but there is a spirit of kindness, love, and humanity that
I'd never experienced in my life prior to going to Ghana. It is my goal to utilize the vibrant
beauty of African culture, dance & music, and weave it into a tapestry of change for the
well-being of the people . Ronnie recently graduated from the University of California Los Angeles in the Master's of African Area Studies program in the spring 2006 and runs S.C.A.D.C.'s volunteer program throughout the year.
