Article Synopsis
  • Trace amines are biologically active amines that resemble traditional monoamines and are quickly broken down by monoamine oxidases, leading to their presence in low quantities.
  • TAAR1 is the primary receptor for trace amines, found in the central nervous system and peripheral areas, and plays a key role in regulating neurotransmission, making it a promising target for treating neuropsychiatric disorders.
  • Recent research highlights TAAR1's potential involvement in neurodegenerative and neurotraumatic disorders, suggesting it could also be a new therapeutic target for these conditions.

Article Synopsis
  • CLN3 Batten disease is a lysosomal storage disorder characterized by retinal degeneration, seizures, motor decline, and early death, with defects in photoreceptor outer segment (POS) phagocytosis observed in patient-derived cells.
  • Researchers used CRISPR to create stem cell lines and a transgenic pig model to explore the effect of CLN3 mutations on POS phagocytosis.
  • Results showed that mutant RPE cells exhibit reduced POS uptake, leading to less efficient phagocytosis and subsequent loss of photoreceptor cells, indicating that both RPE dysfunction and mutant POS contribute to the disease's progression.

Article Synopsis
  • Age-related macular degeneration (AMD) and related macular dystrophies (MDs) primarily impact the retinal pigment epithelium (RPE) with drusen deposits being a key feature in the progression of these diseases.
  • The research indicates that reduced activity of matrix metalloproteinase 2 (MMP2) in RPE contributes to drusen formation by causing sterile inflammation and disrupting lipid balance, interacting with specific receptors and molecules.
  • Therapeutic approaches including MMP2 supplementation and inhibiting RAGE and sPLA2-IIA have shown promise in reducing drusen accumulation in patient-derived RPE cells, highlighting a potential treatment pathway for AMD/MDs.

Medication-related osteonecrosis of the jaw (MRONJ) is a debilitating adverse effect of bisphosphates, antiresorptive therapy or antiangiogenic agents that can potentially increase oxidative stress, leading to progressive osteonecrosis of the jaws. Despite the large number of published systematic reviews, there is a lack of potential MRONJ treatment protocols utilising photobiomodulation (PBM) as a single or adjunct therapy for preventive or therapeutic oncology or non-oncology cohort. Hence, this systematic review aimed to evaluate PBM laser efficacy and its dosimetry as a monotherapy or combined with the standard treatments for preventive or therapeutic approach in MRONJ management.

DPANN archaea are an enigmatic superphylum that are difficult to isolate and culture in the laboratory due to their specific culture conditions and apparent ectosymbiotic lifestyle. Here, we successfully isolated and cultivated a coculture system of a novel Nanobdellota archaeon YN1 and its host Sulfurisphaera ohwakuensis YN1HA. We characterized the coculture system by complementary methods, including metagenomics and metabolic pathway analysis, fluorescence microscopy, and high-resolution electron cryo-tomography (cryoET).

While controlling underwater adhesion is critical for designing biological adhesives and in improving the traction of tires, haptics, or adhesives for health monitoring devices, it is hindered by a lack of fundamental understanding of how the presence of trapped water impedes interfacial bonding. Here, by using well-characterized polycrystal diamond surfaces and soft, nonhysteretic, low-surface energy elastomers, we show a reduction in adhesion during approach and four times higher adhesion during retraction as compared to the thermodynamic work of adhesion. Our findings reveal how the loading phase of contact is governed by the entrapment of water by ultrasmall (10-nanometer-scale) surface features.

Objectives: Mutations in Tissue Inhibitor of Metalloproteinases 3 (TIMP3) cause Sorsby's Fundus Dystrophy (SFD), a dominantly inherited, rare form of macular degeneration that results in vision loss. TIMP3 is synthesized primarily by retinal pigment epithelial (RPE) cells, which constitute the outer blood-retinal barrier. One major function of RPE is the synthesis and transport of vital nutrients, such as glucose, to the retina.

Article Synopsis
  • CLN3 Batten disease is a genetic disorder that begins with vision loss and progresses to seizures, motor decline, and early death; it involves a defect in the ability of retinal pigment epithelial (RPE) cells to clear out photoreceptor outer segments (POSs).
  • Researchers created mutant and control cell lines using CRISPR technology and studied their phagocytosis capabilities, along with examining a genetically modified Yucatan miniswine for further insights.
  • Results showed that RPE cells from mutants had reduced binding and uptake of POSs, leading to less lipofuscin accumulation and significant photoreceptor loss over time, indicating that both RPE dysfunction and mutant POSs play crucial roles in CLN3 disease.
