May 12, 2-16 – A new mouse study done by University of Florida Gainesville researchers has published promising results fighting chronic autoimmune diseases. Their findings can be found in a study published last year in the journal, Science Translational Medicine.
A new drug shows promising results inhibiting metabolic pathways in the immune system. The work which was focused on limiting the metabolism of cancer cells appears to also work on T cells. T cells are the principle cells in our immune system. And lupus, a chronic autoimmune disease is caused by our own T cells attacking healthy cells in our bodies.
About 1.5 million Americans suffer from systemic lupus erythematosus, referred to as lupus, and 16,000 new cases get reported annually. Canada reports about 35,000 cases or 1 in 1,000 of the population. The disease is most common in people between the age of 15 and 45. It has been referred to as having “1,000 faces” because the symptoms vary dramatically and can be confused with other chronic diseases. Typically a person with lupus experiences:
- extreme fatigue
- abnormal swelling of the lower limbs
- seizures
- joint pain
- rashes
- oral sores in the nose and mouth
- abnormal blood chemistry
Lupus patients report several different phases in the disease from flare ups to periods of chronic pain, swelling and rashes. Symptoms can disappear completely going into remission and then flare up again.
The treatment includes anti-inflammatory medication and steroids which have their own dramatic side affects.
The University of Florida team includes co-author Laurence Morel, Ph.D., Director of Experimental Pathology, at the university’s College of Medicine. The focus was on two things within T cells:
- glycolysis, the process by which the body breaks down glutenous to release energy, and,
- mitochondrial metabolism, the source of energy production in cells.
The energy state of immune cells is compromised when lupus occurs. They become hyper activated. So the researchers used two drugs to see if they could block the level of activity. The drugs are 2DG, short for 2-Deoxy-D-glucose, an experimental drug which targets glucose metabolism, and metformin, a commonly used drug for treating patients with Type 2 Diabetes. The application of these two reversed lupus in mice. In testing human T cells harvested from lupus patients,similar results were obtained with a noticeable slowing of cellular metabolism. In mice without lupus the two drugs had no affect on their T cells.
Dr. Morel believes this “may also open the door to targeting other metabolic pathways” replacing treatments for multiple sclerosis, Parkinson’s, Huntington and even Alzheimer’s. It is still no known whether the treatment will produce a complete cure for lupus. It will be a few more years before we will know.
Hello
to everyone in here i am FLORA JAMES from Ohio (UNITED STATE of AMERICA
) I have been suffering from ( LUPUS ) disease for the last four years
and had constant pain, especially in my joint and kidney . During the

have been taking treatment from my doctor, few weeks ago i came on
search on the internet if i could get any information concerning the
prevention of this disease, on my search i saw a testimony of someone
who has been healed from (Hepatitis B and Cancer) by this Man DR IMONAH
and she also gave the email address of this man and advise we should
contact him for any sickness that he would be of help, so i wrote to DR
IMONAH telling him about my (LUPUS) he told me not to worry that i was
going to be cured!! hmm i never believed it,, well after all the
procedures and remedy given to me by this man few weeks later i started
experiencing changes all over me as the Doctor assured me that i am
cured,after some time i went to my doctor to confirmed if i have be
