FS222, a CD137/PD-L1 Tetravalent Bispecific Antibody, Exhibits Low Toxicity and Antitumor Activity in Colorectal Cancer Models.

Purpose: With the increased prevalence in checkpoint therapy resistance, there remains a significant unmet need for additional therapies for patients with relapsing or refractory cancer. We have developed FS222, a bispecific tetravalent antibody targeting CD137 and PD-L1, to induce T-cell activation to eradicate tumors without the current toxicity and efficacy limitations seen in the clinic.

Experimental Design: A bispecific antibody (FS222) was developed by engineering CD137 antigen-binding sites into the Fc region of a PD-L1 IgG1 mAb.

Atypical frontoamygdala functional connectivity in youth with autism.

Functional connectivity (FC) between the amygdala and the ventromedial prefrontal cortex underlies socioemotional functioning, a core domain of impairment in autism spectrum disorder (ASD). Although frontoamygdala circuitry undergoes dynamic changes throughout development, little is known about age-related changes in frontoamygdala networks in ASD. Here we characterize frontoamygdala resting-state FC in a cross-sectional sample (ages 7-25) of 58 typically developing (TD) individuals and 53 individuals with ASD.

Talking with teens about traffic safety: Initial feasibility, acceptability, and efficacy of a parent-targeted intervention for primary care settings.

Introduction: The aims of the current pilot study were to evaluate the feasibility, acceptability, and preliminary efficacy of the Talking with Teens about Traffic Safety Program. The program consists of a clinic-based health coaching session with parents of adolescents at their annual well-child visit to promote parent-teen communication about teen driver safety including: a Parent Handbook that is designed to serve as a primer on teen driver safety and facilitate parent-teen communication on a variety of teen driver topics; an interactive practice driving toolset; and an endorsement of the materials by the primary care provider.

Method: Fifty-four parent-teen dyads (n = 108 total) were recruited from a primary care practice.

Early life stress confers lifelong stress susceptibility in mice via ventral tegmental area OTX2.

Early life stress increases risk for depression. Here we establish a "two-hit" stress model in mice wherein stress at a specific postnatal period increases susceptibility to adult social defeat stress and causes long-lasting transcriptional alterations that prime the ventral tegmental area (VTA)-a brain reward region-to be in a depression-like state. We identify a role for the developmental transcription factor orthodenticle homeobox 2 () as an upstream mediator of these enduring effects.

Families with children conceived by donor insemination: a follow-up at age twelve.

Growing public awareness of the use of donor insemination (DI) to enable infertile couples to become parents has been accompanied by increasing concern regarding the potentially negative consequences for family relationships and child development. Findings are presented from a prospective study of the quality of parenting and psychological adjustment of DI children at age 12. Thirty-seven DI families, 49 adoptive families, and 91 families with a naturally conceived child were compared on standardized interview and questionnaire measures administered to mothers, fathers, children, and teachers.
