Keystone Symposium selects Dr. Alagpulinsa for 2023 Fellows Program

David Alagpulinsa, PhD, Instructor in Medicine and Investigation at the MGH Vaccine and Immunotherapy Center (VIC) and Harvard Medical School, has been selected to participate in the 2023 Keystone Symposia Fellows Program. Commenting on his selection to the program, Dr. Alagpulinsa noted a previous encounter with Keystone Symposia: “Many years ago whilst studying for a master’s degree in Pharmacology in Ghana, I won a Keystone Symposia Global Health Travel Award to attend a Keystone Symposia conference in Banff, Canada. Attending this conference formed the genesis of my scientific career abroad; I felt left out by most of the science that was presented at the conference because I didn’t have the kind of training and expertise to fully understand. Prior to that, I didn’t have any interest in schooling abroad, but I suddenly developed a strong longing to pursue my doctorate degree abroad, specifically the US because most of the scientists I met were from there. Now, I’m here embarking on biomedical research that I’m passionate about, thanks to Keystone Symposia.”

Dr. Alagpulinsa’s current research at VIC focuses on defining the mechanisms that underlie abnormal bone marrow and hematopoietic stem cell function that may contribute to disease etiology, specifically type 1 diabetes and cardiovascular disease.

Expressing gratitude for his selection to participate in the Keystone Symposia Fellows program, Dr. Alagpulinsa comments that “This program aims to provide the necessary training, network, and skills for early-career scientists from diverse populations to take on leadership and decision-making roles in academia or industry and I’m looking forward to having a great experience.”

The Keystone Symposium has served the biomedical and life sciences community for more than 50 years, acting as a key connector between eminent scientists across academic, industry, and government disciplines to provide a space for cross-disciplinary discussion and collaboration that lead to scientific breakthroughs monumental to humankind. Through the Fellows Program, early-career scientists from underrepresented and disadvantaged backgrounds have access to unparalleled professional advancement opportunities including career-development workshops and related hands-on immersion experience, directly collaborating with distinguished scientists of the Scientific Advisory Board. The program focuses on accelerating the career development of selected scientists, generating a network to improve key skills necessary to pursue and achieve career goals.

Novel HIV vaccine approach shows promise in first-in-human clinical trial

Early findings from a publication between Scripps Research, IAVI, Dred Hutch, VRC, and other collaborators show encouraging results in hopes of boosting immunity against HIV. In the first- in-human test of the germline-testing strategy, the novel HIV vaccine approach showed promise, inducing broadly neutralizing antibodies (bnAbs), a rare antibody, previously indicated to protect against a wide range of HIV variants. Through the stimulation of the bnAb immune cells- precursor B cells, researchers have accomplished the first step to potential immunity against HIV.

Investigating Cancer Immunotherapy Effects on COVID-19 Outcomes

Recent findings from research led by University of Cincinnati researcher Trisha Wise-Drapher illuminate the effect of immunosuppression and immunotherapy for patients with cancer and COVID-19. This investigation began with a primary focus on understanding the effects of immunotherapy on COVID-19 severity, specifically if immunotherapy treatment is associated with worse clinical outcomes for cancer patients with COVID-19. The data of 12,046 patients was reviewed and evaluated with metrics including: whether patients were admitted to the hospital, if they required oxygen, or required ICU care. These analyses suggest that patients infected with SARS-CoV-2 that had baseline immunosuppression and followed immunotherapy treatment may have poorer clinical outcomes, whereas patients with immunotherapy alone had no change in outcome quality.

A novel cuproptosis-related immune checkpoint gene signature identification and experimental validation in hepatocellular carcinoma

As current staging systems for cancer are typically found through anatomical evaluations of the disease, stratification of patients for treatment and further therapy strategies prove difficult. Much potential remains in cancer biomarker research for the identification of prognostic gene expression signatures capable of classifying tumor subgroups via their biological counterparts. With the advancements in genomic and transcriptomic technologies, researchers are making great discoveries in cancer biomarkers for detection, prediction of therapeutic response and prognoses of cancer. Recent research highlights a new cuproptosis (copper-induced death) related immune checkpoint gene signature recently investigated as a potential biomarker for anticancer therapy for hepatocellular carcinoma.

Cancer-seeking molecular delivery system could boost immunotherapy drug, research finds

For past decades, the treatment of cancer has generally meant surgery, radiation, chemotherapy, or a combination of the above. Through recent work from a collaboration of researchers from the University of Rhode Island and Yale University comes the promising new approach of delivering immunotherapy agents, STING agonists, via a cancer-seeking molecular delivery system. The delivery relies on the acid-seeking molecule- pHLIP. These molecules deliver cargo directly to the tumor environment via targeting of the high acidity of cancerous tumors. Through this novel drug delivery technique, cancer immunotherapy may become even more effective.
