Coupling of mitochondrial state with active zone plasticity in early brain aging by Lu Fei, Yongtian Liang, Ulrich Kintscher, Stephan J. Sigrist

“…While the two organelles are spaced in close proximity, likely reflecting a direct functional coupling in regard to ATP and Ca2+ homeostasis, the exact modes of coupling in the aging process remain to understood.We here show that genetic manipulations of mitochondrial functional status, which alters brain oxidative phosphorylation, ATP levels, or the production of reactive oxygen species (ROS), can bidirectionally regulate PreScale during early Drosophila brain aging. Conversely, genetic mimicry of PreScale resulted in decreased oxidative phosphorylation and ATP production, potentially due to reduced mitochondrial calcium (Ca2+) import.Our findings indicate the existence of a positive feedback loop where mitochondrial functional state and PreScale are reciprocally coupled to optimize protection during the early stages of brain aging.…”

Antibodies from a Patient with Type 1 Diabetes and Celiac Disease Bind to Macrophages that Express the Scavenger Receptor CD163 by Brigitte Sonier, Alexander Strom, Gen-Sheng Wang, Christopher Patrick, Jennifer A Crookshank, Majid Mojibian, Amanda J MacFarlane, Fraser W Scott

“…Antibodies against the wheat storage globulin Glo-3A from a patient with both type 1 diabetes (T1D) and celiac disease were enriched to identify potential molecular mimicry between wheat antigens and T1D target tissues. …”

Egg retrieval in ground-nesting cuckoo hosts: can two species of buntings accurately identify and retrieve their own eggs? by Yuhan Zhang, Guo Zhong, Longwu Wang, Wei Liang

“…However, both species simultaneously retrieved some (8.3% for the yellow-throated bunting and 19% for south rock bunting) of the highly mimetic budgerigar eggs, indicating that the degree of mimicry of foreign eggs affects their egg recognition and egg retrieval behavior. …”

Autoimmune hepatitis under the COVID-19 veil: an analysis of the nature of potential associations by Chaojie Yu, Wenrui Wang, Qian Zhang, Zhenjing Jin

“…For instance, SARS-CoV-2 may impact autoimmunity through mechanisms such as excessive stimulation of immune responses and molecular mimicry, particularly in genetically predisposed individuals. …”

Secondary Syphilis Presenting as Glossodynia, Plaques en Prairie Fauchée, and a Split Papule at the Oral Commissure: Case Report and Review by Walter de Araujo Eyer-Silva, Maria Alessandra Leite Freire, Cecília Angelina Horta-Araujo, Guilherme Almeida Rosa da Silva, Jorge Francisco da Cunha Pinto, Fernando Raphael de Almeida Ferry

“…Syphilis has been coined “the great imitator” due to its extreme heterogeneity of presentation and mimicry of other conditions. Therefore, it is essential that physicians be familiar with the full spectrum of its manifestations. …”

Mycobacterium avium subsp. paratuberculosis in an Italian Cohort of Type 1 Diabetes Pediatric Patients by Maria Luisa Manca Bitti, Speranza Masala, Francesca Capasso, Novella Rapini, Simona Piccinini, Federica Angelini, Andrea Pierantozzi, Roberta Lidano, Silvia Pietrosanti, Daniela Paccagnini, Leonardo A. Sechi

“…These findings taken together support the hypothesis of MAP as an environmental risk factor for the development of T1D in genetically predisposed subjects, probably involving a mechanism of molecular mimicry between MAP antigens and pancreatic islet β-cells.…”

A novel mode of histone-like protein HupB regulating Sinorhizobium meliloti cell division through lysine acetylation by Ningning Li, Huibo Jin, Hongbo Li, Huilin Yu, Xiaoxu Wu, Tianci Zhang, Liangliang Yu, Zhaoling Qin, Li Luo

“…Mutating these residues to arginine (stimulating non-acetylation) in HupB impedes normal cell division, while substituting them with glycine (mimicking acetylation) allows for rapid cell duplication. The mimicry of non-acetylated HupB leads to enlarged abnormal cells, while stimulating acetylated HupB only reduces cell length. …”

Balancing selection at a wing pattern locus is associated with major shifts in genome-wide patterns of diversity and gene flow by Rodríguez de Cara, María Ángeles, Jay, Paul, Rougemont, Quentin, Chouteau, Mathieu, Whibley, Annabel, Huber, Barbara, Piron-Prunier, Florence, Ramos, Renato Rogner, Freitas, André V. L., Salazar, Camilo, Silva-Brandão, Karina Lucas, Torres, Tatiana Teixeira, Joron, Mathieu

“…H. numata is known to have evolved an inversion supergene which controls variation in wing patterns involved in mimicry associations with distinct groups of co-mimics whereas it is associated to disassortative mate preferences and heterozygote advantage at this locus. …”
