Abstract

Background: Cytotoxic T lymphocytes (CTLs) are key effectors of adaptive immunity, exerting their functions through the release of pro-inflammatory cytokines and cytotoxic molecules. Conditioned medium (CM) derived from CTLs has emerged as a potential cell-free immunotherapeutic strategy; however, the temporal dynamics of its secreted mediators remain poorly defined. Methods: Human CTLs were isolated, activated, and cultured in vitro. CM was harvested at defined intervals (days 5, 10, and 15). Concentrations of interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), perforin, and granzyme-B were quantified by enzyme-linked immunosorbent assay (ELISA). Temporal secretion profiles were evaluated using ANOVA with post-hoc analysis. Results: IFN-γ and TNF-α exhibited peak secretion at day 5, followed by a decline at later time points. In contrast, perforin and granzyme-B increased progressively, reaching maximal levels at day 15. All four mediators demonstrated significant time-dependent variation (p < 0.05). Conclusion: CTL-derived CM displays distinct time-dependent secretion patterns, with cytokines predominating during early activation and cytotoxic molecules dominating later phases. These findings underscore the importance of optimizing CM collection timing to maximize its immunomodulatory and therapeutic potential, and provide a rationale for further translational development of CTL-CM in immunotherapy.

Abstract

Hyperpigmentation of the skin is a result of ultraviolet B (UVB) exposure, which causes oxidative stress due to increased reactive oxygen species (ROS), leading to various skin problems, including melanin accumulation. Exosomes can affect melanocyte activity. Exosomes, as small vesicles released by cells, can affect melanocyte activity and play an important role in various hyperpigmentation processes. The study aims to determine the effect of exosome mesenchymal stem cell hypoxia (EH-MSC) and glutathione with vitamin C on IL-10 levels and CD163 expression. IL-10 gene expression was measured using qRT-PCR, while CD163 expression was analyzed via immunohistochemical staining. A total of 30 male C57BL/6 mice were used and randomly assigned to five different treatment groups. The highest expression of IL-10 was observed in the EH-MSCs-treated group (K4), although the difference was not statistically significant compared to the control (p = 0.135). In contrast, the group receiving a combination of EH-MSCs with glutathione and vitamin C (K5) exhibited the highest percentage of CD163 expression, with a statistically significant difference (p = 0.00). These findings demonstrate that the administration of EH-MSC and glutathione with vitamin C significantly increased the expression of CD163, but insignificantly increased IL-10 in C57BL/6 mice with a UVB-induced hyperpigmentation model.

Abstract

Ischemic stroke is a major global cause of disability and mortality. Inflammation plays a central role in its pathogenesis, characterized by elevated pro-inflammatory cytokines such as IFN-γ and reduced anti-inflammatory cytokines like IL-10. Mesenchymal stem cells (MSCs), especially those derived from the umbilical cord (UC-MSCs), exhibit enhanced immunomodulatory potential when preconditioned under hypoxia. This study aims to evaluate the effect of hypoxic-preconditioned UC-MSCs administration on IFN-γ and IL-10 levels in an ischemic stroke rat model. This in vivo experimental study employed a randomized posttest-only control group design with four groups of male Wistar rats (n=6 each), ranging from healthy controls, untreated group to stroke-induced groups treated with hypoxic UC-MSCs at different doses (1.5x106 and 3x106). IFN-γ and IL-10 levels in brain tissue of each group were measured via ELISA. Significant reduction in IFN-γ and elevation in IL-10 were observed in UC-MSC-treated groups, particularly at the 3×10⁶ cell dose compared to the untreated ischemic group (p<0.05). Hypoxic UC-MSCs reduce post-stroke inflammation by lowering IFN-γ and enhancing IL-10, indicating a promising immunomodulatory potential.

Abstract

Ultraviolet-B (UV-B) radiation-induced skin photoaging is marked by collagen degradation and chronic inflammation, with limited effective treatments currently available. Hypoxic-preconditioned mesenchymal stem cells (H-MSCs) offer a novel therapeutic approach due to their immunomodulatory capabilities. This study evaluated the effects of H-MSCs at two doses (2.5×105 and 5×105 cells) on UVB-induced collagen loss, focusing on CD68 expression and TNF-α levels in a rat model. Male Wistar rats were divided into five groups: healthy controls, UV-B-exposed negative controls (saline), positive controls (hyaluronic acid), and two H-MSC-treated groups. After UV-B exposure (160 mJ/cm², five times per week for two weeks), validated H-MSCs were administered subcutaneously. Collagen content was assessed histologically, while CD68 gene expression and TNF-α levels were measured by qRT-PCR and ELISA, respectively. UVB exposure led to significant reductions in collagen and increased levels of inflammatory markers. H-MSC treatment showed dose-dependent anti-inflammatory effects, with the higher dose (5×105 cells) optimally reducing CD68 expression and TNF-α levels, nearly matching healthy controls. These results suggest that H-MSCs, particularly at higher doses, may be a promising therapy for UVB-induced skin damage and collagen loss.

Abstract

Latar Belakang: Melasma merupakan kelainan hiperpigmentasi yang dipengaruhi oleh faktor hormonal, termasuk penggunaan kontrasepsi hormonal. Kontrasepsi pil dan suntik dapat memicu melasma melalui peningkatan aktivitas melanogenesis. Beberapa penelitian menunjukkan adanya hubungan antara jenis kontrasepsi dengan keparahan melasma, namun data mengenai perbedaan besar pengaruh antara pil dan suntik masih terbatas.Tujuan penelitian: Mengetahui perbedaan besar pengaruh jenis kontrasepsi hormonal pil dan suntik terhadap tingkat keparahan melasma pada pasien di Skin’s Essential Clinic Semarang Tahun 2025.Metode: Penelitian menggunakan desain cross-sectional dengan 37 responden yang memenuhi kriteria inklusi dan eksklusi. Jenis kontrasepsi ditentukan melalui kuesioner, sedangkan tingkat keparahan melasma diukur menggunakan skor MASI. Analisis dilakukan dengan uji Fisher’s Exact untuk menilai hubungan jenis kontrasepsi hormonal dengan tingkat keparahan melasma, serta uji Mann-Whitney untuk menilai perbedaan besar pengaruh antara kedua jenis kontrasepsi terhadap tingkat keparahan melasma.Hasil: Mayoritas pengguna kontrasepsi pil mengalami melasma derajat sedang (42,1%) dan berat (42,1%), sedangkan pengguna kontrasepsi suntik didominasi oleh derajat ringan (50%) dan sedang (44,4%). Berdasarkan uji Fisher’s Exact (p = 0,034) terdapat hubungan bermakna antara jenis kontrasepsi hormonal dengan tingkat keparahan melasma. Uji Mann Whitney menunjukkan perbedaan besar pengaruh yang signifikan antara kedua kelompok (p = 0,005), dengan mean rank pengguna pil lebih tinggi dibanding pengguna suntik, menandakan melasma lebih berat pada kelompok pil.Kesimpulan: Terdapat hubungan dan perbedaan besar pengaruh yang signifikan antara jenis kontrasepsi hormonal pil dan suntik terhadap tingkat keparahan melasma. Pengguna kontrasepsi pil menunjukkan derajat melasma lebih berat dibandingkan pengguna kontrasepsi suntik.
