With the increasing progress in biomedical sciences, to do different modifications at tissue and cell level. I do these modifications to cure a disorder, to prevent an adverse change in metabolism or to strengthen the weakened cells. We also do the modulation of metabolism to improve the body’s internal health. It is done with the help of a new class of drugs which are termed as “Metabolic Modulators”.
“Everyone must choose one of two pains: The pain of discipline or the pain of regret.“
Introduction of Metabolic Modulators:
Metabolic Modulators is introduced to accomplish a new therapeutic target in the treatment of heart failures. These drugs are mainly stated to patients with cardiovascular disorders, specifically for treating heart failure. They modulate cardiac metabolism without the alternation of blood circulation. They also use these drugs for changing particular metabolisms in such a way that the lymphocytes (especially T-Cells) may potentiate, in this way they are vital in the immunotherapy of cancer.
Here in this article, we will provide you with a piece of research-based information about the working of metabolic modulators and their role in strengthening the T-Cells.
How metabolism gets modulated?
They can modulate metabolism in several ways. For Example:
- By adding a new enzyme or compound
- By the inhibition of an enzyme
- By changing the metabolic pathways
“T-Cells are generated in the bone marrow and Educated in the thymus.“
For Heart failure therapy:
Heart failure is a cardiovascular syndrome which may be characterized by reduced oxidation of the tissues of the heart because of deterioration of heart pump function and different parts of the circulatory system. We need to make some changes in the metabolism of the heart tissue’s to replenish the oxygen which is required for a normal pumping of the heart. There are specific contractile-related changes that occur because of switches in myosin profile and change in calcium cycling during diastole and systole. These changes have lessened to keep the normal contraction and relaxation of the heart during the pumping of blood.
RESEARCH study by Hasenfuss et al. has proved that pyruvate can improve the working of heart by augmenting the contractile force and calcium cycling of the myocardium. So the actual thing which is required in this treatment is a drug that produces pyruvate to modulate the metabolism of cardiac muscles so they can efficiently work to pump the blood to other body parts.
Doctors and medical researchers have worked out a new class of drugs which can modulate cardiac metabolism.
When these drugs enter the blood circulation, they act on the tissues of the heart where the reduction of fatty acid metabolism has affected the working of cardiac muscles. They change the metabolism of the heart in such a way that it increases pyruvate production — pyruvate work to improve the myocardial energy, consequently helping in the better contraction of the myocardium.

Role of Metabolic Modulation in potentiating T-Cells:
Medical scientists and researchers have also used particular metabolic modulators to increase the potential of T-cells. Before discussing the role of metabolic modulators in strengthening the T-cells, let us explain what T-cells are and what they do to the human body.
T-Cells are a class of lymphocytes which are part of our immune system. They are found in the thymus gland and play a significant role in the body’s defence. They fight the infections in the body by killing the pathogens and destroying the cancerous cells.
To describe shortly the role of metabolic modulators in potentiating the T-Cells it can be just said that “they increase the strength of T-cells by increasing fatty acid metabolism”. The T-cells can only function properly because of their receptors, and these receptors are fatty acid. When the metabolic modulators augment the fatty acid metabolism, they increase the free fatty acids for the body and the receptors which are naturally fatty acid. As a result, helper T-cells get potentiated and do their work more efficiently to increase the immunity and defend the body against invading pathogens.

CD8+ T-cells and Cholesterol Metabolism:
CD8+ Tells have a primary role in antitumor immunity to fight and kill cancerous cells in the body. Cytotoxicity of CD8+ T-cells reactivated to improve the work in immunotherapy of cancer. These cells are now being potentiated with the help of modulation in the metabolism of cholesterol. Certain metabolic modulators inhibit cholesterol esterification in T-Cells by the pharmacological inhibition of ACT1 (which is a cholesterol esterification enzyme). Through the inhibition of cholesterol, esterification enzymes CD8+ cells may proliferate, and their effect may strengthen; hence it improves their functioning. The experiments proved that the CD8+ cells lacking ACT1 are better than the actual CD8+ cells for controlling the growth of melanoma in mice and also the control of metastasis. The recent clinical trials which tested ‘avasimibe’, an ACT inhibitor, to treat atherosclerosis, found effective in producing a good antitumor effect in humans and melanoma treatment in mice.
Many studies are being done to use metabolic modulators in an even better way to introduce new and effective cancer therapies. It modulates different metabolic pathways to improve the efficiency of T-cells. Research studies have shown that membrane lipids also can regulate T-cell immune response and signalling because cholesterol is the major component of the membrane lipids. They are required for the clustering of receptors of T-Cells (TCR) and formation of the immunological synapse of T-Cells.
Potentiating the antitumor response of CD8(+) T cells by modulating cholesterol metabolism and identifying the role of T cells in the modulation of cholesterol metabolism. The research by Yang et al. in 2016 and published in NCBI. The shadows of this blog come from nature.com blogs because Nature.com is the best place to find the latest scientific research. Modulation of Metabolism to potentiate T-cells related study was published in nature explaining different aspects.
