Role of SARS-CoV-2 mutations in the evolution of the COVID-19 pandemic

P. Colson, H. Chaudet, J. Delerce, P. Pontarotti, A. Levasseur, J. Fantini, B. La Scola, C. A. Devaux, D. Raoult

The paper analyzes SARS-CoV-2 mutations across 61,397 genomes to identify 'hyperfertile' mutations that spread widely, finding most did not predict new epidemic forms, with some in non-coding regions and stop codons.

Sexually dimorphic activation of innate antitumour immunity prevents adrenocortical carcinoma development

J. J. Wilmouth, J. Olabe, D. Garcia-Garcia, C. Lucas, R. Guiton, F. Roucher-Boulez, D. Dufour, C. Damon-Soubeyrand, I. Sahut-Barnola, J.-C. Pointud, Y. Renaud, A. Levasseur, I. Tauveron, A.-M. Lefrancois-Martinez, A. Martinez, P. Val

This study shows that sexually dimorphic activation of innate antitumour immunity prevents adrenocortical carcinoma development, with male-specific macrophage responses driving tumour regression.

PKA drives paracrine crisis and WNT4-dependent testis tumor in Carney complex

C. Djari, I. Sahut-Barnola, A. Septier, I. Plotton, N. Montanier, D. Dufour, A. Levasseur, J. Wilmouth, J.-C. Pointud, F. Faucz, C. Kamilaris, A.-G. Lopez, F. Guillou, A. Swain, S. J. Vainio, , A. M. Lefrancois-Martinez

The paper investigates the role of PKA in Carney complex testis tumors, showing that Prkar1a mutations in both stromal and Sertoli cells drive LCCSCTs via WNT4-dependent paracrine signaling.

Dramatic HIV DNA degradation associated with spontaneous HIV suppression and disease-free outcome in a young seropositive woman following her infection

P. Colson, C. Dhiver, C. Tamalet, J. Delerce, O. Glazunova, M. Gaudin, A. Levasseur, D. Raoult

The paper identifies a HIV-1-seropositive woman who spontaneously suppressed HIV replication and found that dramatic HIV DNA degradation occurred, likely due to extrinsic factors like the gut microbiota.
