Background: Cerebral adrenoleukodystrophy is a severe form of X-linked adrenoleukodystrophy characterized by white-matter disease, loss of neurologic function, and early death. Elivaldogene autotemcel (eli-cel) gene therapy, which consists of autologous CD34+ cells transduced with Lenti-D lentiviral vector containing complementary DNA, is being tested in persons with cerebral adrenoleukodystrophy.

Methods: In a phase 2-3 study, we evaluated the efficacy and safety of eli-cel therapy in boys with early-stage cerebral adrenoleukodystrophy and evidence of active inflammation on magnetic resonance imaging (MRI).

Article Synopsis
  • Gene therapy using elivaldogene autotemcel (eli-cel) has shown effectiveness in treating cerebral adrenoleukodystrophy but raises concerns about cancer risks.
  • Research analyzed blood and bone marrow samples from patients who received eli-cel to evaluate integration sites and other genetic factors.
  • Out of 67 patients treated, 7 developed hematologic cancers, with multiple instances linked to lentiviral vector insertions, though some patients successfully underwent stem cell transplantation and remained symptom-free.

Skilled activity is a complex mix of automatized action, changed attention patterns, cognitive strategies and physiological adaptations developed within a community of practice. Drawing on physiological and ethnographic research on freediving, this article argues that skill acquisition demonstrates the variety of mechanisms that link biological and cultural processes to produce culturally shaped forms of embodiment. In particular, apneists alter phenotypic expression through patterned practices that canalize development, exaggerating the dive response, developing resistance to elevated carbon dioxide levels (hypercapnia) and accommodating hydrostatic pressure at depth.

We present an 'Ecological Resilience Framework' (ERF) to demonstrate how resilience is created through the Justice Ambassadors Youth Council (JAYC) program. JAYC is a platform in which New York government representatives collaboratively learn and develop policy solutions alongside emerging adults who are criminal legal system impacted and reside in predominantly Black and Hispanic communities characterized by chronically high levels of poverty, violence, and incarceration. We focus our work on the process of developing resilience in the context of structural social inequity and injustice.
