Summary
January’s cosmetic research was defined by translational biomaterials, disease-responsive dermal delivery, and procedure-level innovations that preserve function and aesthetics. Top signals include a druggable collagen–integrin pathway linking environmental nanoplastics to neurodegeneration, an intranasal BBB-bypass nanolamellar system enabling sequential mitochondria-targeted therapy, and a CRISPR-enabled platform for scalable human type III collagen with in vivo wound-healing efficacy. Dermal pipeline advances featured CD44/CES2-targeted hyaluronic acid–butyrate conjugates that prioritize skin retention and inflammation-triggered release. Randomized surgical evidence supported gasless endoscopic thyroidectomy for better cosmetic satisfaction and neck function without compromising short-term oncologic outcomes.

1. Nanoplastics trigger glial-neuronal collagen signaling miscommunication to exacerbate cognitive impairment in Alzheimer's disease.
In APP/PS1 mice, 90-day oral polystyrene nanoplastic exposure worsened cognition and hippocampal injury while augmenting collagen–integrin-mediated neuroglial signaling. Pharmacologic integrin blockade (TC‑I 15) attenuated collagen activation and rescued cognition. Human single‑nucleus RNA‑seq corroborated upregulated collagen signaling in AD brains, indicating a translatable, druggable exposure–disease pathway.
Impact: Uncovers a mechanistic, druggable collagen–integrin link between environmental nanoplastic exposure and AD progression, with cross-species validation and therapeutic rescue.
Clinical Implications: Supports public health strategies to limit micro/nanoplastic exposure and motivates exploration of collagen–integrin inhibitors or biomarkers in at-risk AD populations; human translational studies remain necessary.
Key Findings
- Nanoplastic exposure exacerbated cognitive deficits and hippocampal injury in APP/PS1 mice.
- Collagen–integrin neuroglial signaling was strengthened and pharmacologic integrin blockade rescued cognition.
- Human single‑nucleus RNA‑seq confirmed upregulated collagen signaling in AD brains.
2. Intranasal blood-brain barrier bypass enables sequential mitochondria-targeted bioengineered nanolamellar system for ischemic stroke therapy.
MM@BPPF, a microglia–mitochondria hybrid biomembrane-coated black phosphorus nanosheet carrying PolyMet and FTY720, achieved inflammation-directed brain targeting and homotypic mitochondrial targeting. Intranasal administration bypassed the BBB, increased brain accumulation, and enabled sequential restoration of neuronal mitochondrial function and microglial polarization in ischemia–reperfusion models.
Impact: Establishes a biomimetic, sequential-targeting intranasal nanoplatform that bypasses the BBB and targets mitochondria—opening new CNS delivery paradigms.
Clinical Implications: Suggests organelle-level drug delivery via intranasal route for stroke and other CNS disorders; requires GLP safety, chronic dosing, and translational PK/PD prior to human trials.
Key Findings
- Developed MM@BPPF nanosheets with dual microglia–mitochondria biomembranes carrying PolyMet and FTY720.
- Achieved inflammation-directed brain targeting and homotypic mitochondrial targeting.
- Intranasal administration bypassed the BBB and enabled sequential mitochondrial restoration and glial modulation.
3. CRISPR-engineered zebrafish expression system for human type III collagen: Therapeutic efficacy in wound healing.
A CRISPR/Cas9 transgenic zebrafish platform expressed human Col3a1 to yield a collagen composite with high thermal stability and intact fibrillar architecture. In vitro assays showed anti-inflammatory modulation and fibroblast proliferation, and murine wound models achieved >95% closure by day 15 with improved neoskin thickness and collagen deposition.
Impact: Demonstrates a scalable production route for functionally intact human type III collagen with in vivo efficacy, bridging biomaterials engineering and therapeutic dermatology.
Clinical Implications: If immunogenicity and GMP manufacturing are addressed, the platform could enable next-generation dressings, scaffolds, or dermal regeneration products for reconstructive and aesthetic indications.
Key Findings
- CRISPR/Cas9 zebrafish expressed human Col3a1 to produce a thermally stable collagen composite with intact fibrillar architecture.
- In vivo murine models showed >95% wound closure by day 15 with improved neoskin thickness and collagen deposition.
- In vitro assays demonstrated anti-inflammatory modulation and enhanced fibroblast proliferation.
4. Hyaluronic acid-butyrate conjugates for barrier restoration in atopic dermatitis: CD44-mediated retention and inflammation-responsive release.
Hyaluronic acid–butyrate conjugates, especially 5 kDa HAB, enhanced skin retention ~6.5-fold over free butyrate via CD44 targeting and CES2-triggered local release in inflamed skin. In DNFB-induced AD mice, 5k-HAB accelerated lesion resolution, reduced TEWL and erythema, restored hydration and barrier proteins, and mitigated oxidative stress and inflammatory cytokines.
Impact: Validates a disease-responsive dermal delivery platform that prioritizes retention over penetration with mechanistic (CD44/CES2) and in vivo efficacy.
Clinical Implications: Supports development of HA-based topical formulations for AD that enhance local efficacy while reducing systemic exposure; next steps include ex vivo human skin testing and early-phase trials.
Key Findings
- 5k-HAB increased skin retention ~6.5-fold versus free butyrate in IVPT using normal and AD-like skin.
- Targeting and local release were mediated by CD44 overexpression and elevated CES2 in inflamed skin.
- In AD mice, 5k-HAB improved TEWL, erythema, hydration, barrier proteins, and reduced oxidative stress and cytokines.
5. Functional and cosmetic advantages of gasless endoscopic thyroidectomy in papillary thyroid carcinoma: a randomized trial.
In a randomized trial (n=90) comparing gasless endoscopic subclavicular approach (ESSA) with open hemithyroidectomy+CND, ESSA matched oncologic metrics (lymph node yield, 6-month recurrence) and complications while significantly improving anterior neck sensory/motor function and cosmetic satisfaction.
Impact: Randomized evidence that a minimally invasive, gasless approach preserves neck function and improves cosmesis without compromising short-term oncologic safety.
Clinical Implications: ESSA can be considered when anterior neck function and cosmetic outcomes are prioritized, with attention to training requirements and longer-term oncologic follow-up.
Key Findings
- Oncologic metrics (lymph node yield, 6-month sonographic recurrence) and complications were comparable between ESSA and open surgery.
- ESSA significantly improved anterior neck sensory (P=0.0217) and motor function (P=0.008).
- ESSA achieved higher cosmetic satisfaction (P<0.001) with similar safety.
