Sinclair’s Information Theory of Aging posits that aging is largely caused by corrupted instructions in the cell’s DNA (known as epigenetic). This can be reset using partial cellular reprogramming.
This involves activating Yamanaka genes to turn cells into stem cells but for shorter durations than in full cellular reprogramming. His team has already used this technique to make blind mice see again.
Stem Cells
Stem cells have the ability to transform into different types of cell in our body, serving as a repair system. Scientists are excited about stem cells because they may one day help us to cure serious diseases like cancer and Parkinson’s disease. They may also help explain how certain conditions like birth defects and spinal cord injuries come about.
Researchers have discovered that by treating existing stem cells with a rejuvenating combination of proteins, they can rewind the molecular clock and make them appear nearly indistinguishable from young stem cells. Known as the Yamanaka factors, these rejuvenating proteins are used to turn adult cells into so-called induced pluripotent stem cells (iPS) that can be turned into any type of cell in the body. When injected into the body, these iPS cells can then replace the damaged or aging cells.
Scientists have found that by infusing older patients with iPS cells from healthy younger patients, the old patient’s blood cells exhibit improved function and reduced inflammation. The results from these clinical trials have led to a significant increase in the number of clinics offering human iPS cell therapy. Unfortunately, not all of these clinics are created equal. When considering a regenerative medicine program, it is important to work with a COFEPRIS-licensed and MHLW-notified clinic that offers live stem cell therapy using the most advanced protocols in a safe clinical environment. A trusted clinic will be able to provide documentation of sourcing, screening, cell handling, and sterility controls that demonstrate the highest quality of care and patient safety.
When injected into your bloodstream, stem cells are able to detect chemical signals (cytokines, chemokines, growth factors) released by your damaged or aging tissues and migrate there. This is called “homing.” They can treat a myriad of health conditions, from rheumatoid arthritis and lupus to aging frailty and depleted muscle reserves.
The benefits of regenerative medicine are long-term and progressive, with results emerging over weeks to months rather than immediately. This is because the treatment works at a biological level to improve repair signaling, calm harmful inflammation, and support better function over time. When placed within a holistic longevity plan that includes dietary change, NAD+ protocols, peptide therapy, and targeted IV treatments, stem cell therapy can help you achieve and maintain your desired results for years to come.
Gene Therapy
Gene therapy is a type of treatment that uses DNA to target disease-causing genes. The goal is to change the gene’s behavior or replace it with a healthy one. This can treat many diseases, including some that may cause aging. For example, some types of cancer are caused by genes that don’t work properly or stop working altogether. By replacing these genes with healthy ones, healthcare professionals can restore the cells’ ability to function properly.
There are several different methods scientists use to introduce genetic material into cells for gene therapy. Most of them involve putting the new gene into a package that can get inside your cells. The package is called a vector. Viruses are often used as vectors because they can carry genetic materials into cells. But the viruses used for gene therapy must be engineered so that they can’t make you sick.
Scientists can also introduce genes into cells using a technique called lentiviral gene transfer. This method involves using a special kind of virus to deliver the genes into cells. It’s similar to how a vaccine works, except the viruses don’t directly attack your body’s cells.
Once a gene has been introduced into your cells, it can start producing the protein it’s supposed to produce. In some cases, this protein may prevent the cell from growing or dividing. In other cases, it may help the cell fight infection or damage.
Gene therapies are a major step-change from traditional pharmaceuticals, which treat symptoms but can’t change the underlying causes of a disease. They can also be more effective than other treatments for certain conditions, especially those that affect the whole body.
Researchers are developing new ways to make these therapies more effective. They’re also testing the potential of chemical compounds to reverse cellular aging. This research is a step toward transforming the aging process from a disease that we have to live with to one that can be prevented or treated.
Cellular Rejuvenation
Cellular rejuvenation refers to the reversal of the biological processes that cause an organism’s cells to deteriorate as they age. A healthy lifestyle and a diet rich in antioxidants are good ways to slow the process of aging, but new drugs and technologies can also be used to rejuvenate cells.
One such technology is partial cellular reprogramming, which involves adding a mixture of four reprogramming factors to cells in order to reset their epigenetic state and bring them closer to the pluripotent stem cell (iPSC) state. This method has been shown to significantly slow down cellular aging in in vitro culture and in mice, but further research is needed to determine how effective it will be in human cells.
Another approach to cellular rejuvenation involves treating non-dividing cells such as senescent cells, which are associated with the development of various age-related diseases and can cause chronic inflammation in the body. In a recent study, Izpisua Belmonte and his team found that long-term treatment with Yamanaka factors can cause senescent cells to rejuvenate and return to the replicative state. This results in a reduction in the production of toxic molecules and increases the work of systems that clear away cellular debris.
Rejuvenating senescent cells also leads to an increase in mitochondrial function, which can reduce the risk of developing degenerative conditions such as neurodegeneration, metabolic syndrome and cardiovascular disease. However, further studies are needed to determine whether the same effects would be seen when using the Yamanaka factors in human cells.
The team is now exploring the possibility of reversing the aging of blood-forming stem cells by reversing the defects that affect their growth and regenerative potential. A paper published in the journal Cell Stem Cell identifies the cause of these defects as hyperactivation and dysfunction of the stem cells’ lysosomes. Reversing these abnormalities can restore a more normal state of lysosomal degradation, which in turn revives the stem cells’ ability to regenerate blood-forming tissues.
The researchers hope that the reversal of the cellular aging process will lead to the discovery of new treatments for diseases and disorders caused by abnormal cell division or the accumulation of cellular waste products. This could include cancer and neurodegeneration, as well as the loss of stem cell function that occurs in many different types of tissue.
Immunotherapy
Your immune system is a complex collection of organs, proteins, and chemicals that fight infections and disease by tracking germs and other abnormal cells. Most of the time, it is able to find and destroy cancer cells as they arise. However, cancer can develop ways to hide from the body’s immune system or suppress its activity. Immunotherapy aims to restore your immune system’s ability to identify and attack cancer cells.
Immunotherapy can be combined with other treatments, including chemotherapy and radiation therapy. The immunotherapy can boost the effects of these treatments and increase your chance of achieving long-term remission.
Immunotherapies may be used to treat a wide range of cancer types. They include vaccines, cell therapies, and cytokines (a group of biological substances that are naturally produced in your body to help your immune system fight cancer).
A type of immunotherapy known as cellular therapy involves taking cells from your body, modifying them in the lab so they can better attack cancer cells, then returning the modified cells to your body to kill cancer. The FDA has approved several cellular therapy treatments, such as chimeric antigen receptor (CAR)-T cell therapy and tumor-infiltrating lymphocyte (TIL) therapy.
Other forms of immunotherapy work by enhancing the immune response with drugs, such as antibodies or cytokines. Antibodies are lab-made proteins that target and bind to cancer cells or other targets. The FDA has approved several antibodies, such as monoclonal antibodies that bind to specific tumor cells and radioactive isotopes that bind to the cancer cell’s surface.
For some cancers, such as melanoma skin cancer, a drug called talimogene laherparepvec (T-VEC) uses a weakened form of the herpes simplex virus that infects and destroys cancer cells. Immunotherapy is an exciting area of research. Our experts are always evaluating new options and improving existing therapies.
Immunotherapy can cause side effects, including flu-like symptoms, skin reactions, and inflammation. Immunotherapy can also cause a delay in your body’s normal blood clotting process and make you more vulnerable to infection. Your health care team can help you manage these side effects.
