In this study, researchers analyzed over 5,000 T cells per sample using scRNA+TCR-seq technology and found that dual TCR Tregs are present in high proportions across various mouse tissues, showing unique TCR pairing patterns, V(D)J usage, and mRNA expression compared to single TCR Tregs.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

This case report highlights that a patient with resistance to thyroid hormone was misdiagnosed as having Graves’ disease, leading to unnecessary radioactive iodine treatment.

This study found that in wild-type Arabidopsis plants, root hair growth is suppressed with increased nutrient availability, with RHD6 subfamily genes down-regulated and GTL1 and DF1 genes influencing root hair morphology under these conditions.

This study identified a novel mechanism by which dsRNA-induced TLR3 activation and retinoic acid pathways contribute to new hair follicle formation after deep wounds in mice and suggested a similar potential in humans.

TEDAR is crucial for skin cell differentiation and barrier formation.

LRIG1 protein affects hair growth by regulating skin receptors, leading to hair loss when overexpressed.

This study found that overexpression of the transcription factor Tcf3 accelerates keratinocyte migration and skin wound healing in mice, highlighting its potential as a therapeutic target for wound repair.

This study found that expressions of TLR-3, TLR-7, TLR-8, and TLR-9 were significantly higher in alopecia areata patients compared to healthy controls, indicating a potential role in disease autoimmunity.

This study identifies a mechanism where dsRNA activates TLR3 to induce RA production, promoting hair follicle regeneration in mice and suggesting a potential role in human tissue regeneration.

In this study, deletion of ROBO4 in mice ameliorated hair loss caused by elevated PAF levels, suggesting potential interplay with VLDLR-related pathways.

In this study, a patient with recalcitrant lichen planopilaris and frontal fibrosing alopecia showed significant improvement after receiving four doses of the interleukin-23 monoclonal antibody tildrakizumab.

In this study, TLR1 gene polymorphism rs4833095 was significantly associated with increased susceptibility to alopecia areata in the Korean population.

This study identified "HTLV-1-associated lichenoid dermatitis" as a skin condition in HTLV-1-infected individuals, characterized by reactive eruptions associated with increased immunity toward infected CD4+ T cells.

In this study, a 532 nm laser at 15 J/cm² increased the proliferation and tenogenic differentiation of tendon-derived stem cells in rats, mediated by Nr4a1 up-regulation.

In this case report, a 20-year-old male with tricho-rhino-phalangeal syndrome was found to have a de novo frameshift mutation in the TRPS1 gene, highlighting the challenges in diagnosing this rare disorder.

This study investigated dual TCR Treg cells in mouse tissues, revealing a high proportion and diverse pairing patterns compared to single TCR Tregs, providing insights into their origins and characteristics across different tissue locations.

This study reported that a modified version of Thymosin beta 4, called PEG-rTβ4, demonstrated potential as a treatment for acute myocardial infarction by improving cardiac function and reducing cell death via specific biochemical pathways, suggesting its promise in drug development efforts.

This study found that a phosphorus starvation-insensitive mutant of Arabidopsis thaliana shows altered root growth and auxin responses under low phosphate conditions compared to wild-type plants, suggesting a role for LPR1 in regulating these traits.

The researchers reported two brothers with a new variant of X-linked trichothiodystrophy associated with an RNF113A gene mutation, highlighting features such as intellectual disability and growth failure, but without previously reported endocrinological or genital abnormalities, underlining the importance of genetic counseling for such variants.

RNase L suppresses regeneration in mammals.

This study found that the retinoid LGD1069 suppressed mammary tumorigenesis in a mouse model without observable toxicity, while TTNPB showed modest effects but was associated with significant toxicity.
