AI Article Synopsis

  • Rodent models play a crucial role in studying kidney development and diseases such as acute kidney injury (AKI) and its progression to chronic kidney disease (CKD).
  • Recent advancements have allowed researchers to create models that reflect various causes of AKI and its related complications, aiding both basic research and drug development.
  • However, these models have significant limitations in accurately representing human conditions, highlighting the need for improved models that better mimic the complexities of human kidney disease.

Article Abstract

Despite known drawbacks, rodent models are essential tools in the research of renal development, physiology, and pathogenesis. In the past decade, rodent models have been developed and used to mimic different etiologies of acute kidney injury (AKI), AKI to chronic kidney disease (CKD) transition or progression, and AKI with comorbidities. These models have been applied for both mechanistic research and preclinical drug development. However, current rodent models have their limitations, especially since they often do not fully recapitulate the pathophysiology of AKI in human patients, and thus need further refinement. Here, we discuss the present status of these rodent models, including the pathophysiologic compatibility, clinical translational significance, key factors affecting model consistency, and their main limitations. Future efforts should focus on establishing robust models that simulate the major clinical and molecular phenotypes of human AKI and its progression.

Purpose: This study aimed to identify a novel recombinant adeno-associated virus (rAAV) capsid variant that can widely transfect the deep retina through intravitreal injection and to assess their effectiveness and safety in gene delivery.

Methods: By adopting the sequences of various cell-penetrating peptides and inserting them into the capsid modification region of AAV2, we generated several novel variants. The green fluorescent protein (GFP)-carrying variants were screened following intravitreal injection.

The HOX and PBX genes encode transcription factors that have key roles in development and cancer, both independently and as a heterodimer within a complex of proteins that recognizes specific sequences in DNA and can both activate and repress transcription of target genes. Due to functional redundancy amongst HOX proteins, knock down or knock out studies of individual genes often do not result in an altered phenotype. An alternative approach is to target the interaction between HOX and PBX proteins, which is dependent on a conserved hexapeptide region within HOX.

In clinics, physical injuries to the spinal cord cause a temporary motor areflexia below lesion, known as spinal shock. This topic is still underexplored due to the lack of preclinical spinal cord injury (SCI) models that do not use anesthesia, which would affect spinal excitability. Our innovative design considered a custom-made micro impactor that provides localized and calibrated strikes to the ventral surface of the thoracic spinal cord of the entire CNS isolated from neonatal rats.

Human GABAergic inhibitory neurons (INs) in the telencephalon play crucial roles in modulating neural circuits, generating cortical oscillations, and maintaining the balance between excitation and inhibition. The major IN subtypes are based on their gene expression profiles, morphological diversity and circuit-specific functions. Although previous foundational work has established that INs originate in the ganglionic eminence regions in mice, recent studies have questioned origins in humans and non-human primates.

Targeting the influencing factors in tumor growth and expansion in the tumor microenvironment is one of the key approaches to cancer immunotherapy. Various factors in the tumor microenvironment can in cooperation stimulate tumor growth, suppress anti-tumor immune responses, promote drug resistance, and ultimately enhance tumor recurrence. Therefore, due to the dependence and close cooperation of these axes, their combined targeting can have a greater effect compared to their individual targeting.
