Maternal-Infant Respiratory Syncytial Virus and Influenza A Virus Antibody Transfer in Preterm and Full-term Infants.

Background: Immunization against influenza and respiratory syncytial virus (RSV) protects pregnant individuals and their infants against infection via transplacental transport of immunoglobulin G (IgG). We sought to evaluate the quantity and efficiency of maternal influenza- and RSV-specific IgG transfer in pregnancies with preterm and full-term deliveries.

Methods: Delivery samples from 115 maternal-infant pairs (2018-2021) were analyzed for RSV prefusion F and IAV-H3 and IAV-H1 antibodies using electrochemiluminescence assays.

Biochemically plausible models of habituation for single-cell learning.

The ability to learn is typically attributed to animals with brains. However, the apparently simplest form of learning, habituation, in which a steadily decreasing response is exhibited to a repeated stimulus, is found not only in animals but also in single-cell organisms and individual mammalian cells. Habituation has been codified from studies in both invertebrate and vertebrate animals as having ten characteristic hallmarks, seven of which involve a single stimulus.

Evaluation of Transplacental Maternal SARS-CoV-2 Antibody Transfer in Small for Gestational Age Infants.

Little is known about the potential benefits of maternal immunization in the setting of high-risk pregnancies resulting in small-for-gestational-age (SGA) infants. This study compares transplacental transfer of maternal SARS-CoV-2 anti-Spike antibody in pregnancies with SGA compared to appropriate-for-gestational-age infants.

Transfer of Respiratory Syncytial Virus Prefusion F Protein Antibody in Low Birthweight Infants.

Background: Respiratory syncytial virus (RSV)-associated lower respiratory tract infection contributes significantly to morbidity/mortality worldwide in low birthweight (LBW) infants (<2500 g). Studies have demonstrated decreased maternal immunoglobulin G (IgG) transfer of various antibodies to LBW infants. We aimed to evaluate naturally acquired RSV anti-prefusion F protein (anti-preF) antibody transfer in pregnancies with LBW versus normal birthweight (NBW) infants.
