Retrotrans-genomics identifies aberrant THE1B endogenous retrovirus fusion transcripts in the pathogenesis of sarcoidosis by Shunsuke Funaguma, Aritoshi Iida, Yoshihiko Saito, Jantima Tanboon, Francia Victoria De Los Reyes, Kyuto Sonehara, Yu-ichi Goto, Yukinori Okada, Shinichiro Hayashi, Ichizo Nishino

“…Single-cell or single-nucleus RNA-seq analyses of sarcoidosis not only confirmed these transcripts but also revealed a novel read-through transcript, SIRPB1-SIRPD, and TREM2.1, predominantly in granuloma-associated macrophages. The expression profiles of THE1B fusion transcripts in tuberculosis (TB) significantly differed from SM in single-cell RNA-seq data, suggesting that the differences between TB’s caseous granulomas and sarcoidosis’s non-caseous granulomas might be linked to disparate expression patterns of THE1B fusion transcripts. …”

iPSC-Derived Retinal Pigment Epithelium Allografts Do Not Elicit Detrimental Effects in Rats: A Follow-Up Study by Peter D. Westenskow, Felicitas Bucher, Stephen Bravo, Toshihide Kurihara, Daniel Feitelberg, Liliana P. Paris, Edith Aguilar, Jonathan H. Lin, Martin Friedlander

“…We observed no gross abnormalities in the eyes, livers, spleens, brains, and blood in aging rats with iPSC-RPE grafts. iPS-RPE cells that integrated into the subretinal space outlived the photoreceptors and survived for as long as 2 1/2 years while nonintegrating RPE cells were ingested by host macrophages. Both populations could be distinguished using immunohistochemistry and electron microscopy. iPSC-RPE could be isolated from the grafts and maintained in culture; these cells also phagocytosed isolated photoreceptor outer segments. …”

2-Aminothiophene Derivatives—New Drug Candidates Against Leishmaniasis: Drug Design, Synthesis, Pharmacomodulation, and Antileishmanial Activity by Rodrigo Santos Aquino de Araújo, Vitória Gaspar Bernardo, Robert da Silva Tibúrcio, Danilo Cesar Galindo Bedor, Michel Leandro de Campos, Roberto Pontarolo, Julyanne Maria Saraiva de Sousa, Klinger Antonio da Franca Rodrigues, Marcus Tullius Scotti, Anuraj Nayarisseri, Pascal Marchand, Francisco Jaime Bezerra Mendonça-Junior

“…<b>Methods</b>: Dozens of 2-AT and 2-aminoselenophen (2-AS) derivatives were sequentially synthesized through applications of the Gewald reaction and were then evaluated in vitro for their activities against <i>L. amazonensis</i> and for cytotoxicity against macrophages. <b>Results</b>: Several series of compounds were synthesized, and it was possible to identify some substitution patterns favorable to the activity generating compounds with IC₅₀ values below 10 µM, such as the non-essentiality of the presence of a carbonitrile group at C-3; the importance of the presence and size of cycloalkyl/piperidinyl chains at C-4 and C-5 in modulating the activity; and the increase in activity without affecting the safety of the S/Se bioisosteric substitution. …”
