iCART and iPSCs Opens New Doors in Cell Therapy

The human induced pluripotent stem cell (iPSC) research landscape is rapidly evolving. We recently discussed the current trend in stem cell research to streamline the production of induced pluripotent stem cells (iPSC) from peripheral blood mononuclear cells (PBMCs).  Recent exciting studies have indicated that harnessing iPSCs self-renewal ability to manufacture cell therapies is now becoming a reality. Just 4 years ago, the pharmaceutical company Takeda and The Center for iPS Cell Research and Application (CiRA) at Kyoto University entered a 10-year joint research collaboration. A few weeks ago, it was announced that Takeda has advanced the first product from its collaboration with CiRA - a highly scalable off-the-shelf CAR-T cell therapy to treat cancer - into pre-clinical development.[1] Here, we briefly discuss the iCART science behind the Takeda study and its potential implications for an “off-the-shelf” CAR-T cell therapy.

PBMC Reprogramming Opens Doors in Regenerative Medicine

New clinical applications in regenerative medicine are motivating an intense interest in easily accessible sources for producing human stem cells. The 2007 breakthrough showing that induced pluripotent stem cells (iPSC) could be generated directly from adult cells has been a boon to the industry. Since that time, there has been a steady refinement of the cell culture techniques that guide the cell reprogramming process.

Developing Treatments for Sclerosis Patients

Systemic sclerosis, also called scleroderma, progressive systemic sclerosis, or CREST syndrome, is a rare autoimmune connective tissue disease with fibrosis and vasculopathy. Patients often have sclerotic, thickened skin, but some experience significant organ damage. Immunosuppressive therapy is a common approach to patients with systemic sclerosis, but there is a subset of patients that do not respond well to treatment.

Chronic Stress May Increase Cellular Aging in Women

A study using peripheral blood mononuclear cells (PBMCs) demonstrates the link between women’s stress levels and shortened telomere length.

Stress is one of the body’s major means of reacting to life challenges, dangers, and difficulties. Various chemicals are released in the body that promote cellular and organ-level changes needed to cope with, adjust, and respond to stressors. The effects that are felt with chronic stress range anywhere from pain, digestive problems, and fatigue to sexual, cognitive, immunological, and emotional effects. Women are particularly vulnerable to the effects of stress due to unique challenges they face, including gender and race-based discrimination and forms of victimization.

PBMCs and Psoriasis Treatments

Scientists examined the peripheral blood mononuclear cell (PBMC) profiles of patients with and without psoriasis, including those that both responded to classic treatments and didn’t respond. They then analyzed the profile of those immune cell types. Here are the results of that study.

There are often differences among patient populations for a given disease in how effective a treatment provides medical relief. An important part of personalized medicine is identifying patients that are not likely to respond to a treatment regimen for a specific disease or condition. Doing this can limit the loss of time and resources in using ineffective treatments and can allow the use of personalized treatments in these populations.
