AUTISM SPEAKS Weatherstone Predoctoral Fellow Recipient 2017
Under the mentorship of Shafali Jeste, at the University of California-Los Angeles, Ms. Tran will use noninvasive electroencephalography (EEG) to identify early differences in brain connectivity in infants at high familial risk for autism. Her study will also assess whether these differences can predict language development and autism symptom severity. This work aims to improve early identification and personalized interventions that can support and improve each child’s development.

Memory-Induced Chaos in Cardiac Excitation
Julian Landaw, Alan Garfinkel, James N. Weiss, and Zhilin Qu
Phys. Rev. Lett. 118, 138101 – Published 28 March 2017
Excitable systems display memory, but how memory affects the excitation dynamics of such systems remains to be elucidated. Here we use computer simulation of cardiac action potential models to demonstrate that memory can cause dynamical instabilities that result in complex excitation dynamics and chaos. We develop an iterated map model that correctly describes these dynamics and show that memory converts a monotonic first return map of action potential duration into a nonmonotonic one, resulting in a period-doubling bifurcation route to chaos.

Background Approximately 75% of objective responses to anti-programmed death 1 (PD-1) therapy in patients with melanoma are durable, lasting for years, but delayed relapses have been noted long after initial objective tumor regression despite continuous therapy. Mechanisms of immune escape in this context are unknown. Methods We analyzed biopsy samples from paired baseline and relapsing lesions in four patients with metastatic melanoma who had had an initial objective tumor regression in response to anti-PD-1 therapy (pembrolizumab) followed by disease progression months to years later. Results Whole-exome sequencing detected clonal selection and outgrowth of the acquired resistant tumors and, in two of the four patients, revealed resistance-associated loss-of-function mutations in the genes encoding interferon-receptor-associated Janus kinase 1 (JAK1) or Janus kinase 2 (JAK2), concurrent with deletion of the wild-type allele. A truncating mutation in the gene encoding the antigen-presenting protein beta-2-microglobulin (B2M) was identified in a third patient. JAK1 and JAK2 truncating mutations resulted in a lack of response to interferon gamma, including insensitivity to its antiproliferative effects on cancer cells. The B2M truncating mutation led to loss of surface expression of major histocompatibility complex class I. Conclusions In this study, acquired resistance to PD-1 blockade immunotherapy in patients with melanoma was associated with defects in the pathways involved in interferon-receptor signaling and in antigen presentation.

Esther Nie was awarded the prestigious Eva Kavan Prize for Excellence in Research on the Brain on June 14, 2016
The Eva Mary Kavan Prize for Excellence in Research on the Brain was established in 1999 by a generous endowment from Dr. Eva Kavan.  Dr. Kavan earned her doctorate degree in medicine at Charles University in her native Prague, Czechoslovakia.  She came to UCLA in 1956 at a time when there were only five hospitals performing open-heart surgery with a heart-lung machine; UCLA had one of the first teams to do open-heart surgery in the West. Dr. Kavan was a pioneer in the administration of anesthesia, utilizing the electroencephalogram to perform important research on the effects of the heart-lung machine on brain function during open-heart operations.  Dr. Kavan created this award to encourage a talented young scholar to pursue scientific research on the brain.

Dr. Stephen Young, a UCLA cardiologist and molecular geneticist who works on understanding mechanisms for human disease, has been elected to the National Academy of Sciences — one of the highest honors that can be bestowed on a scientist — in recognition of his “distinguished and continuing achievements in original research.”
The National Academy of Sciences announced today the election of 84 new members and 21 foreign associates from 14 countries.
Young, a distinguished professor of medicine and human genetics at the David Geffen School of Medicine at UCLA, focuses on two areas of research — plasma triglyceride metabolism and the role of nuclear envelope proteins in health and disease.
