Article Abstract
Background: Exosomes, nano-sized vesicles ranging between 30 and 150 nm secreted by human cells, play a pivotal role in long-range intercellular communication and have attracted significant attention in the field of regenerative medicine. Nevertheless, their limited productivity and cost-effectiveness pose challenges for clinical applications. These issues have recently been addressed by cell-derived nanovesicles (CDNs), which are physically synthesized exosome-mimetic nanovesicles from parent cells, as a promising alternative to exosomes. CDNs exhibit structural, physical, and biological properties similar to exosomes, containing intracellular protein and genetic components encapsulated by the cell plasma membrane. These characteristics allow CDNs to be used as regenerative medicine and therapeutics on their own, or as a drug delivery system.
Methods: The paper reviews diverse methods for CDN synthesis, current analysis techniques, and presents engineering strategies to improve lesion targeting efficiency and/or therapeutic efficacy.
Results: CDNs, with their properties similar to those of exosomes, offer a cost-effective and highly productive alternative due to their non-living biomaterial nature, nano-size, and readiness for use, allowing them to overcome several limitations of conventional cell therapy methods.
Conclusion: Ongoing research and enhancement of CDNs engineering, along with comprehensive safety assessments and stability analysis, exhibit vast potential to advance regenerative medicine by enabling the development of efficient therapeutic interventions.

Stemming from human immune organs, tonsil-derived mesenchymal stem cells (TMSCs) hold unique strengths in differentiation potential and immune regulatory functions. These characteristics make them valuable for therapeutic applications, particularly in regenerative medicine and autoimmune disease treatment, as they can modulate immune responses and promote tissue repair. Their ability to interact with various cell types and secrete a range of bioactive molecules further enhances their role in orchestrating healing processes, making them a promising avenue for innovative therapies aimed at restoring balance in the immune system and facilitating recovery from injury or disease.

Purpose: To evaluate visual outcomes after bacterial keratitis (BK) and identify predictive factors for poor prognosis at a tertiary referral center in Southern California.
Methods: This is a cross-sectional retrospective review of patients' medical records with culture-positive BK at University of California Los Angeles from January 1, 2014, to December 31, 2019. Main outcome measure was change in best-corrected visual acuity (BCVA) at 12 weeks posttreatment.

Hydrogel-based bioinks are widely adopted in digital light processing (DLP) 3D printing. Modulating their mechanical properties is especially beneficial in biomedical applications, such as directing cell activity toward tissue regeneration and healing. However, in both monolithic and granular hydrogels, the tunability of mechanical properties is limited to parameters such as cross-linking or packing density.

Despite the success of antiretroviral therapy in suppressing plasma viremia in people living with human immunodeficiency virus type-1 (HIV-1), persistent viral RNA expression in tissue reservoirs is observed and can contribute to HIV-1-induced immunopathology and comorbidities. Infection of long-lived innate immune cells, such as tissue-resident macrophages and microglia may contribute to persistent viral RNA production and chronic inflammation. We recently reported that de novo cytoplasmic expression of HIV-1 intron-containing RNA (icRNA) in macrophages and microglia leads to MDA5 and MAVS-dependent innate immune sensing and induction of type I IFN responses, demonstrating that HIV icRNA is a pathogen-associated molecular pattern (PAMP).

Cystic Fibrosis (CF) is a multiorgan disease caused by mutations in the gene, leading to chronic pulmonary infections and hyperinflammation. Among pathogens colonizing the CF lung, is predominant, infecting over 50% of adults with CF, and becoming antibiotic-resistant over time. Current therapies for CF, while providing tremendous benefits, fail to eliminate persistent bacterial infections, chronic inflammation, and irreversible lung damage, necessitating novel therapeutic strategies.
