Abstract

Neuroinflammation, an inflammatory response within the central nervous system (CNS), plays a critical role in various neurological disorders, including neurodegenerative diseases. Alpha linolenic acid (ALA), an essential omega-3 polyunsaturated fatty acid, has shown promising health benefits due to its antioxidant and anti-inflammatory properties. This article aims to thoroughly examine the potential effects of ALA in reducing neuroinflammation, emphasizing its roles as an anti-inflammatory and antioxidant agent. The review focuses on studies published between 2018 and 2023, sourced from reputable academic databases such as PubMed, Semantic Scholar, Google Scholar, and ScienceDirect, with nine key papers selected. The findings indicate that ALA significantly mitigates neuroinflammation by decreasing reactive oxygen species (ROS) via the Nrf-2/HO-1/JNK signaling pathway. Additionally, ALA reduces inflammatory cytokines by inhibiting p-JNK activation, disrupting lipid rafts, blocking the pro-inflammatory transcription factor NF-κB, and altering cell membrane phospholipid composition. The review concludes that ALA may have potential therapeutic effects in reducing neuroinflammation through its antioxidant and anti-inflammatory actions, offering possible benefits for various neurological conditions, including Alzheimer's and Parkinson's diseases.

Abstract

Oryzias hubbsi's distribution is rarely discussed, as it is believed to only occupy the western part of Java, while its conservation status is Near Threatened (NT) as of 15 October 2018 on the IUCN red list. Specimens of O. hubbsi were recorded from Bandung and Jakarta in the description, other reports for O. hubbsi are commonly from Southern Sumatra-Western Java (SWJ) ecoregion in Java. However, an unexpected discovery of the genus Oryzias in Semarang freshwater opens up opportunities for the hidden spread of O. hubbsi to Central Java, and especially to other ecoregions which is Central and East Java (CEJ). Morphological approaches with distinctive O. hubbsi characters, complemented by molecular approaches with O. hubbsi samples from the Bogor population, confirmed similarities of species between both populations. Genetic distance using p-distances between both populations was below 2%, both populations made obvious clusters with a gap of 0.5%, and differed by five nucleotide base sites only. This new distribution record of O. hubbsi can be a foundation for conservation and domestication planning efforts.
