The interleukin-7 (IL-7) signaling pathway plays an essential role in the development, proliferation and homeostasis of T and B cells in cell-mediated immunity. Understimulation and overstimulation of the IL-7 signaling pathway leads to severe combined immunodeficiency, autoimmune reactions, heart disease and cancers. Stimulation of the IL-7 pathway begins with IL-7 binding to its alpha-receptor, IL-7R alpha. Protein crystals of unglycosylated and glycosylated complexes of human IL-7-IL-7R alpha extracellular domain (ECD) obtained using a surface entropy-reduction approach diffract to 2.7 and 3.0 A, respectively. Anomalous dispersion methods will be used to solve the unglycosylated IL-7-IL-7R alpha ECD complex structure and this unglycosylated structure will then serve as a model in molecular-replacement attempts to solve the structure of the glycosylated IL-7-alpha-receptor complex.

The highly variable 22q11 deletion syndrome has been proposed for addition to newborn screening panels. A literature review investigated the incidence and prevalence, clinical features, and prognosis of 22q11 deletion syndrome and other issues related to newborn screening. Severe complications that could potentially be helped by screening include cardiac defects in 80% (with 20% having no outward signs to aid detection), hypocalcemia that can lead to seizures in 20% (though hypocalcemia is routinely investigated in sick newborns), and severe immune deficiency in <1% (which would be identified by some states' severe combined immunodeficiency screens). Other benefits that do not fit traditional goals of newborn screening include treatment for complications such as failure to thrive and developmental delay or preventing a "diagnostic odyssey." Although universal screening may prove the incidence to be >1:5000, undetected life-threatening effects occur in a minority of 22q11 deletion syndrome patients. Concerns include an untested screening technique, difficulty obtaining results in time for cardiac intervention, the chance of "vulnerable child syndrome" in mild cases, and possibly detecting congenital heart disease more efficiently by other means. Because addition of tests for highly variable conditions such as 22q11 deletion syndrome is likely to set a precedent for other syndromes, reevaluation of newborn screening criteria should be considered.

Numerous poxviruses infect humans and animal hosts, and a poxvirus vaccine with an improved safety profile is needed as the current vaccinia virus vaccine is contraindicated in individuals that have a history of eczema or heart disease, or are immunocompromised or pregnant. In addition, poxviruses make excellent vaccine vectors for other infectious diseases and cancer. Raccoonpoxvirus is a naturally occurring attenuated North American poxvirus, and thus it is of interest as a vaccine vector platform. This study explores the effects of raccoonpoxvirus in SCID and Nude immunocompromised and pregnant mouse models to assess its virulence and probable safety for human and animal populations. We also analyzed the safety of recombinant raccoonpox carrying a gene expressing a foreign antigen, rabies virus glycoprotein, designed for heterologous vaccine protection. Our data show that recombinant raccoonpoxviruses are avirulent in many cases and are much safer than vaccinia virus (strain WR). Raccoonpoxviruses also have the advantage of being able to replicate in mammalian cells. This allows increased immunogenicity and production efficiency, giving an advantage over non replicating vectors such as Modified Vaccinia Ankara MVA or canarypoxvirus.

Newborn screening in the United States is an important public health measure to provide early detection for specified disorders when early treatment is both possible and beneficial. As technology improves, newborn screening can be offered for many more conditions. In the past 10 years, screening has expanded to include severe combined immunodeficiency, congenital heart disease, lysosomal storage disease, and X-linked adrenoleukodystrophy. This article reviews the current state of newborn screening with updates on recent developments. [Pediatr Ann. 2018;47(5):e187-e190.].

Severe infection with the re-emerging enterovirus 71 (EV71 or EV-A71) can cause cardiopulmonary failure. However, in patients' heart and lung, viral protein has not been detected. In mouse models, heart disease has not been reported. EV71-infected brainstem is generally believed to be responsible for the cardiopulmonary collapse. One major limitation in EV71 research is the lack of an efficient oral infection system using non-mouse-adapted clinical isolates. In a robust oral infection NOD/SCID mouse model, we detected EV71 protein at multiple organs, including heart and lung, in 100% of moribund mice with limb paralysis. Infiltrating leukocytes were always detected in heart and muscle, and VP1-positive M2 macrophages were abundant in the lung. Functional dissection on the pathogenesis mechanism revealed severe apoptosis, inflammatory cytokines, and abnormal electrocardiogram (EKG) in orally infected hearts. Therefore, cardiopulmonary disease could be one plausible cause of death in this mouse model. Inoculation of EV71 through an oral route resulted in viral infection in the intestine, viremia, and EV71 appeared to spread to peripheral tissues via blood circulation. Infectious virus was no longer detected in the blood on day 5 post-infection by the plaque formation assay. We demonstrated that both EV71 clinical isolate and cloned virus can target the cardiopulmonary system via a natural infection-like oral route.
