This study identified a “core” immune signature in the peripheral blood of COVID-19 patients. Blood T cells were typically characterized by co-existing lymphopenia and highly activated/proliferative phenotype, especially in severe patients. Some signature traits, including basophil and plasmacytoid dendritic cell depletion, and T cell-cycling, correlated with disease severity. Notably, a triad of molecules — IP-10, interleukin-10 and interleukin-6— anticipated disease worsening.
The study, called COVID-IP, was led by prof. Adrian Hayday (Francis Crick Institute, King’s College London, London, UK). A cohort of 63 hospitalized COVID-19 patients at Guy’s and St Thomas’ Hospitals (London, UK) was studied. Dr. Francesca Di Rosa (Institute of Molecular Biology and Pathology, CNR, Rome, Italy) was a member of the international team. She contributed to the novelty by introducing the innovative T cell assay for cell cycle analysis, that was used for the first time in COVID-19 patients in this study.

The identification in living cells of the protein FUS, crucially involved in Amyotrophic Lateral Sclerosis (ALS), as a direct interactor of HOTAIRM1 in motoneurons, together with the presence of a cytoplasmic isoform of HOTAIRM1 in motoneuron soma and neurites (yellow arrows), open the way for investigating a possible implication of this noncoding transcript in neurodegeneration.

This study highlights a novel role of the metabolic enzyme serine hydroxymethyl transferase (SHMT), in supporting the high proliferative capacity of cancer cells.
Cancer cells, especially in particularly aggressive tumors, e.g. lung carcinoma, have increased nutritional demands compared to normal cells. Understanding how tumor cells reprogram their metabolism to meet these demands, therefore, is key to understand the mechanisms that support the aberrantly high proliferation rate of cancer cells. The researchers have now identified a specific RNA that binds to and controls the function of the SHMT enzyme in the cytoplasm, while at the same time regulating the expression of a specific isoform found in mitochondria, the energy-producing centers of the cell.
The discovery paves the way for innovative therapies, aimed at designing nucleic acid molecules capable to act as metabolic "switches", so as to starve the tumor cells and hence block their proliferation.
This collaborative study is a joint effort between researchers from the Department of Biochemical Sciences "A. Rossi Fanelli" at the University La Sapienza and the Institute of Molecular Biology and Pathology (IBPM-CNR), in collaboration with the Department of Biology and Biotechnology (Sapienza), the Center for Genomic Regulation of Barcelona and the Catalan Institute of Oncology of Girona.

During mitotic division genomic DNA is equally partitioned between the daughter cells, and several cellular machineries are reorganized to ensure faithful chromosome segregation. For example, cellular processes such as transcription and mRNA processing (“splicing”) are shut down during mitosis. The work by Pellacani et al. shows that two splicing factors, Sf3A2 e Prp31, are not inactive during mitosis but directly mediate proper kinetochore- microtubule interactions. These findings open the way to future research aimed at identifying new “moonlighting proteins” involved in both nuclear processes occurring during interphase and regulation of mitosis. An accurate understanding of mitosis at the molecular level is crucial to elucidate the mechanisms of tumorigenesis and develop new anti-cancer therapies.
