The immune system is traditionally thought to be exclusively nuclear-encoded. Here, we report the identification of a mitochondrial-encoded host defense peptide (HDP) that presumably derives from the primordial proto-mitochondrial bacteria. We demonstrate that MOTS-c (mitochondrial open reading frame from the twelve S rRNA type-c) is a mitochondrial-encoded amphipathic and cationic peptide with direct antibacterial and immunomodulatory functions, consistent with the peptide chemistry and functions of known HDPs. MOTS-c targeted <i>E. coli</i> and methicillin-resistant <i>S. aureus</i> (MRSA), in part, by targeting their membranes using its hydrophobic and cationic domains. In monocytes, IFNγ, LPS, and differentiation signals each induced the expression of endogenous MOTS-c. Notably, MOTS-c translocated to the nucleus to regulate gene expression during monocyte differentiation and programmed them into macrophages with unique transcriptomic signatures related to antigen presentation and IFN signaling. MOTS-c-programmed macrophages exhibited enhanced bacterial clearance and shifted metabolism. Our findings support MOTS-c as a first-in-class mitochondrial-encoded HDP and indicates that our immune system is not only encoded by the nuclear genome, but also by the co-evolved mitochondrial genome.</p>","PeriodicalId":15836,"journal":{"name":"Journal of Geophysical Research","volume":"117 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11565950/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79976467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Canalolith repositioning maneuvers, including Epley, Semont, and Gans maneuvers, have been recommended for treating posterior canal BPPV with a high rate of success. A prospective, quasi-randomized study was carried out to compare the efficacy of Epley, Semont, and Gans maneuvers in the treatment of posterior canal BPPV and their durability. All patients over the age of 20 who met the BPPV diagnostic criteria, regardless of gender, were included in the study. Diagnosis of BPPV was done by Dix Hallpike maneuver. Typical posterior canal BPPV, the most frequent form of BPPV, is characterized by paroxysmal nystagmus evoked through the Dix-Hallpike test; the nystagmus is torsional clockwise for the left side, counter-clockwise for the right side, with a vertical up-beating component. The patients were uniformly quasi-randomized in a 1:1:1 ratio to be treated with Epley, Semont, and Gans maneuvers. After performing the maneuver, the patients were again subjected to the Dix-Hallpike test. Based on the result of the Dix-Hallpike test's positivity, the maneuvers were repeated up to three times. All the patients were called for a reassessment 30 days after the last intervention to assess the durability of the maneuver. In the study, 54.44% (49) of the 90 patients were female, whereas 45.56% (41) were male. Overall, 83.33% (75) of patients required only one attempt, 15.56% (14) required two attempts, and 1.11% (1) required three attempts to improve. In the Epley maneuvers group, 86.66% (26) required only one attempt, 10% (3) required two attempts, and 3.33% (1) required three attempts. Similarly, 83.33% (25) required only one attempt in the Gans maneuvers group, and 16.67% (5) required two attempts. In Semont maneuver groups, 80% (24) required only one attempt, and 20% (6) required two attempts. The recurrence of the symptoms was seen in a total of 11 patients: 27.27% (3 patients) of the Epley maneuvers group, 36.36% (4 patients) of the Gans maneuvers group, and 36.36% (4 patients) of the Semont maneuvers group.

The sorghum-sudangrass production data collected between 1988 and 2013 were compiled along with the production year's weather data. The growing degree days (GDD), accumulated rainfall, and sunshine duration were used to assess their impacts on forage production (kg/ha) trend. Conversely, GDD and accumulated rainfall had positive and negative effects on the trend of forage production, respectively. Meanwhile, weather events such as heavy rainfall and typhoon were also collected based on weather warnings as weather events in the Korean monsoon season. The impact of weather events did not affect forage production, even with the increasing frequency and intensity of heavy rainfall. Therefore, the trend of forage production for the sorghum-sudangrass hybrid was forecasted to slightly increase until 2045. The predicted forage production in 2045 will be 14,926 ± 6,657 kg/ha. It is likely that the damage by heavy rainfall and typhoons can be reduced through more frequent harvest against short-term single damage and a deeper extension of the root system against soil erosion and lodging.
