Abstract

Shallot (Allium cepa var. aggregatum L.) is an important commodity in horticulture and Indonesian foods. In Bantul Regency, Yogyakarta, Indonesia, shallot twisted diseases caused by Fusarium spp. significantly reduced yield quality and quantity. Supportive condition for plant-pathogen interaction needed for twisted disease development. This research aimed to measure the twisted disease incidence and observe the cultivation practice applied by shallot farmers in the Bantul coastal area as environmental aspects of the twisted disease to be a pre-study for further research on metagenomic analysis. This research had conducted in three sub-villages with different agroecosystems in the coastal area: Sono, Samiran, and Depok. Data were collected in shallot cultivation period in dry and rainy seasons from three farmers of each area. The higher disease incidence in the rainy season occurred in the Samiran sub-village at 33.97%, while in the dry season, disease incidence occurred in the Depok sub-village at 20.14%. Sono sub-village had the lowest disease incidence in rainy and dry seasons at 12.44% and 0%. Farmer cultivation practice may drive disease incidence due to environmental factors such as shallot variety, spacing between plants, fertilizer, and fungicides. Hence, further study is needed to understand plant-pathogen interaction with metagenomics through samples from 2 and 6 WAP in rainy seasons.

Abstract

Background: Mesenchymal stem cells (MSCs) are known for their immunomodulatory properties, particularly their ability to secrete anti-inflammatory cytokines such as interleukin-10 (IL-10). Enhancing the secretion of IL-10 by MSCs could have significant therapeutic potential for treating inflammatory diseases. Objective: This study aimed to prime the secretion of IL-10 by MSCs through the use of conditioned medium (CM) derived from lipopolysaccharide (LPS)-induced peripheral blood mononuclear cells (PBMCs). Methods: MSCs were isolated from Wharton’s Jelly and characterized using flow cytometry and differentiation assays. PBMCs were isolated from human blood samples and stimulated with LPS to produce a pro-inflammatory environment. The conditioned medium from these LPS-induced PBMCs was collected and add to MSCs culture medium in 5% and 7.5%. After 24h and 48h incubation, IL-10 secretion by MSCs was measured using an enzyme-linked immunosorbent assay (ELISA). Results: The results demonstrated that MSCs cultured in the conditioned medium from LPS-induced PBMCs showed a significant increase in IL-10 secretion compared to control conditions in 24h exposure, but not significantly different in 48h. Conclusion: The exposure of conditioned medium from LPS-induced PBMCs may effectively enhances the secretion of IL-10 by MSCs.
