Direct prion neuroinvasion following inhalation into the nasal cavity.

mSphere

December 2024

Department of Medical Microbiology and Immunology, School of Medicine, Creighton University, Omaha, Nebraska, USA.

Inhalation of prions into the nasal cavity is an efficient route of infection. Following inhalation of infectious prions, animals develop disease with a similar incubation period compared with per os exposure, but with greater efficiency. To identify the reason for this increased efficiency, we identified neural structures that uniquely innervate the nasal cavity and neural structures known to mediate neuroinvasion following oral infection and used immunohistochemistry to determine the temporal and spatial accumulation of prions from hamster tissue sections containing cell bodies and axons at 2-week intervals following prion exposure.

Adolescence is a period of profound biopsychosocial development, with pubertally-driven neural reorganization as social demands increase in peer contexts. The explosive increase in social media access has fundamentally changed peer interactions among youth, creating an urgent need to understand its impact on neurobiological development and mental health. Extant literature indicates that using social media promotes social comparison and feedback seeking (SCFS) behaviors in youth, which portend increased risk for mental health disorders, but little is known about its impact on neurobiological development.

Beijing Institute of Mathematical Sciences and Applications, Beijing 101408, China; Yau Mathematical Sciences Center, Tsinghua University, Beijing 100084, China; Shanghai Institute for Mathematics and Interdisciplinary Sciences, Shanghai 200433, China. Electronic address:

Despite being challenging, elucidating the systematic control mechanisms of multifactorial drug responses is crucial for pharmacogenomic research. We describe a new form of statistical mechanics to reconstruct informative, dynamic, omnidirectional, and personalized networks (idopNetworks), which cover all pharmacogenomic factors and their interconnections, interdependence, and mechanistic roles. IdopNetworks can characterize how cell-cell crosstalk is mediated by genes and proteins to shape body-drug interactions and identify key roadmaps of information flow and propagation for determining drug efficacy and toxicity.

Bradykinin is an endogenously produced nonapeptide with many physiological and pathological functions that are mediated by two pharmacologically defined receptor subtypes, B1- and B2-receptors. Current studies sought to characterize the functional bradykinin (BK) receptors present in freshly isolated bovine ciliary muscle (BCM) using an organ-bath tissue contraction system. Cumulative longitudinal isometric tension responses of BCM strips (4-5 mm) were recorded before and after the addition of test compounds to BCM strips hooked up to an isometric strain gauge transducer system.

Article Synopsis
  • Elevated intracranial pressure during vaginal delivery may lead to neonatal retinal hemorrhage by causing stress and deformation in the eye's structures.
  • A computational model showed how maternal contractions can displace the eye backward, inducing strain in the retina and stress on retinal vessels.
  • The study suggests that the resulting eye deformation, rather than blockage of blood vessels, is a more likely cause for this type of retinal damage in newborns.

The K antigen is a major cause of hemolytic disease of the fetus and newborn (HDFN). K-HDFN is unique in that it can result in destruction of not just mature erythrocytes but fetal erythrocyte progenitors, causing severe fetal anemia earlier in pregnancy than other antigens. This poses a danger to fetal health as intrauterine transfusion (IUT), the preferred method of managing HDFN, becomes riskier earlier in pregnancy.
