'Humanized' mice will lead to better testing of cancer immunotherapies

(University of Colorado Denver) New model reported in Oncogene, XactMice, uses human blood stem cells to grow a 'humanized' mouse immune system prior to tumor transplantation, allowing anti-cancer therapies to be tested in a much more human-like environment.

Oral mucositis is a significant complication of cancer therapy because of the associated pain and negative effects on the ability to eat, drink, and swallow and on the quality of life. Furthermore, oral mucositis increases the risk of systemic infection, and may interrupt cancer therapy. Oral mucositis manifests as erosions or ulcerations of the nonkeratinized oral mucosa, and its course depends on the form of cancer therapy. Oral mucositis affects an estimated 14% to 81% of patients undergoing some forms of chemotherapy, begins within days of initiating treatment, and lasts for up to 2 weeks depending on the dose, intensi...

This study investigated long-term risk and therapeutic endpoints including hepatitis B surface antigen (HBsAg) seroclearance following antiviral therapy in patients developing reactivation of resolved HBV.MethodsThe study included 528 consecutive HBsAg-negative/hepatitis B core antibody-positive patients who underwent rituximab treatment or hematopoietic stem cell transplantation (HSCT) between 2006 and 2016. Long-term outcomes of patients with reactivation after antiviral therapy were examined in comparison with 37 HBsAg-positive chronic carriers under the same medical settings.ResultsThe 7-year cumulative rate of HBV rea...

Discussion Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in ...

AbstractPurpose of ReviewCellular therapy started in the early twentieth century with the development of blood transfusion and later bone marrow transplantation. This review describes the historical origins and major milestones in the field of cellular therapy. We discuss ethical concerns associated with certain cell sources and how they influenced therapy strategies. A focus of this article is on the use of stem cells to understand regenerative repair after kidney injury. In addition, we give an overview over past and current kidney-related cellular therapy trials.Recent FindingsThe number of kidney-related cellular thera...

Jim Mellon's Juvenescence venture is at present one of the few major venture organizations focused on approaches to treat aging as a medical condition. Mellon and his colleagues outlined their take on the field in a 2017 book, also called Juvenescence. We are fortunate in that he is among the first few high net worth individuals to both agree with the SENS philosophy of damage repair, and then, much more importantly, follow through in action as well as word. He is not just seeing a massive market opportunity in treating aging, though that is certainly there, but is doing this because he wishes to achieve the goal of radica...

I am a little late with the 2019 list of projects in rejuvenation biotechnology that I'd like to see startups tackling sometime soon. In my defense, this year I have a startup of my own to keep up with, and the first part of 2019 was a wall to wall series of conferences alternating between the US and Europe. It continues to be the case that this is a new industry of near endless potential, yet little of that potential is under active development. This is the state of affairs despite the arrival of hundreds of millions of dollars in venture funds managed by the like of Juvenescence, Life Biosciences, and so on. The research...

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...

For years, cancer treatment was dominated by chemotherapy, radiation therapy, and stem cell transplantation. New insights into genetic characteristics of leukemic cells have initiated the development of the chimeric antigen receptor (CAR) T-cell therapy. This type of adoptive cell immunotherapy has been a breakthrough in the treatment of aggressive B-cell lymphoma and B-cell precursor acute lymphoblastic leukemia. In August 2018, the European Commission has approved the first CAR T-cell products – tisagenlecleucel (Kymriah®, Novartis) and axicabtagene ciloleucel (Yescarta®, Gilead) – for hematological n...
