Role of Myeoloid-Derived Suppressor Cells in Septic Shock Immunoparalysis
 Role of Myeoloid-Derived Suppressor Cells in Septic Shock Immunoparalysis 1024 683 Mary Bates, PhD
By: Mary Bates, PhD

New study is the first to describe increased myeloid-derived suppressors cells in children with septic shock. In children with septic shock, the immune system initiates a systemic inflammatory response and a nearly concurrent compensatory anti-inflammatory response. When severe, this anti-inflammatory response is termed “immunoparalysis” and is associated with increased risk of infections and death. Researchers…

A review of antibody titers for SMA patients revealed that levels may decrease with time, potentially enabling delayed dosing for children who otherwise might have been excluded from life-saving gene therapy. Adeno-associated viral (AAV) vectors are used to deliver gene therapies such as onasemnogene abeparvovec-xioi (ZOLGENSMA®), a recently approved gene therapy for spinal muscular atrophy…

International program facilitates the diagnosis of a rare immunodeficiency in two children caused by a novel genetic variant. A multidisciplinary team of physicians and scientists at Nationwide Children’s Hospital have identified a novel loss-of-function variant causing CARMIL2 deficiency, an inborn error of immunity, in two Saudi Arabian brothers born to consanguineous parents. The case was…

Researchers work to reveal the many subtypes of pediatric sepsis — and what to do about them. Once upon a time, sepsis was just sepsis. Children experiencing septic shock and its aftermath — any resulting organ failure — were viewed as a fairly homogenous group of patients. But now, thanks in a large part to…

By: Katie Brind'Amour, PhD, MS, CHES

Now that physicians have the “how” of blood transfusions mastered, they are starting to explore the “what” — and they’re learning that the effects of sharing human blood may be even more far-reaching and complex than previously imagined. With the initial safety challenges addressed and the technical barriers of donor blood storage and cleaning improved,…

Harnessing the Immune System: Has the Cure for Cancer Been Within Us All Along?
 Harnessing the Immune System: Has the Cure for Cancer Been Within Us All Along? 1024 575 Abbie Miller
By: Abbie Miller

By learning to manipulate the immune system to target cancer cells, clinician-scientists are ushering in a new era in cancer treatments. The advances in cancer immunotherapy have been headline-making, and some clinical studies have produced stories of near-miraculous recoveries. From the immunotherapy drug credited with curing former president Jimmy Carter’s cancer (pembrolizumab) to the promising…
