Summary: Cyclophilins (Cyps), a subgroup of peptidyl-prolyl cis-trans isomerases (PPIases) with a highly conserved domain, play important roles in various intracellular signaling pathways and are implicated in the development of diseases such as cardiovascular diseases, neurodegeneration, and cancer. Their involvement in viral infection as regulators of intercellular communication has attracted increasing attention, as viral proteins can target specific motifs of Cyps to manipulate infection outcomes.

Summary: This study characterized a conserved and a more divergent cyclophilin isoform from Toxoplasma gondii. The conserved isoform showed high activity and affinity for CsA, while the divergent isoform had low activity and was less sensitive to CsA inhibition. Structural studies revealed differences in the CsA-binding site between the two isoforms, suggesting distinct functions in the parasite.

Summary: A prognostic model based on 3 peptidyl prolyl cis-trans isomerase gene signatures was constructed for hepatocellular carcinoma patients. The model showed that patients in the high-risk score group had a worse prognosis, and the validation results were consistent with the training set. A nomogram incorporating clinical stage and risk score was established with a well-matched calibration curve.

Summary: Pin1 regulates the structure and function of eukaryotic RNA polymerase II through interaction with Rpb1 in response to oxidative stress, facilitating transcription elongation. Elevated Pin1 levels in cancer cells may help sustain survival under oxidative stress. These findings suggest a conserved function of Pin1 in cellular response to oxidative stress among eukaryotic cells with potential clinical implications.

Summary: This study compares the conformational dynamics of cyclophilin isoforms and identifies key dynamic residues in the gatekeeper 2 region that are essential for their catalytic activity. The highly conserved glycine residue (Gly80) is predicted to contribute to the local flexibility, which is further confirmed by molecular dynamics simulations on mutants (G80A) of CypE and CypA. The mutations lead to changes in flexibility and catalytic behavior of CypE and CypA, suggesting a loss of function.

Summary: Both PrsA isoforms play unique and overlapping roles in maintaining GAS proteome homeostasis and virulence-associated traits. Inactivation of both PrsA proteins in GAS leads to significant impairment in biofilm formation, host adherence, infection-induced cytotoxicity, and in vivo virulence in a murine soft tissue infection model. The concordance of proteomic and phenotypic data highlights the essential role of PrsA in full virulence of GAS.

Summary: A study reveals that the immunophilin CYP28 regulates the assembly and accumulation of photosystem II-light-harvesting complex II supercomplexes in plant chloroplasts. The lack of CYP28 results in accelerated leaf growth, earlier flowering time, and increased accumulation of high molecular weight PSII-LHCII supercomplexes. CYP28 likely alters the configuration of Lhcb6 through its PPIase activity to regulate the accumulation of PSII-LHCII supercomplexes.

Summary: Human cyclophilin A (hCypA) interacts strongly with the viral SARS-CoV-2 receptor-binding domain (RBD), blocking the binding of RBD to angiotensin-converting enzyme 2 (ACE2) receptor, thereby suppressing the entry of coronavirus into host cells. This suggests that hCypA may be a potential target for antiviral therapy.

Summary: Communicable diseases spread quickly through infectious mediums among people and animals, such as bacteria and viruses. The recent global outbreak of COVID-19 has motivated researchers to use smart sensor technologies to detect, prevent, and control the spread of communicable diseases. Smart sensors, including biosensors, wearable sensors, unmanned vehicles, and bedsheet sensors, collect real-time data on the transmissibility of diseases, which can be processed using advanced machine-learning techniques. The use of smart sensors helps facilitate more accurate diagnoses of communicable disease viruses.

Summary: Emotions and gestures are crucial in improving social intelligence and predicting human actions. Deep neural networks have become popular in recognizing visual actions, but classifying ambiguous actions remains challenging. This article proposes an attention-aware DNN called HAANet, which captures long-term temporal context to recognize actions in videos. HAANet extracts discriminative features of facial expressions and gestures in both spatial and temporal dimensions. The effectiveness of HAANet is demonstrated on benchmark datasets, and a new dataset called VALC is created to focus on the visual cues of human actions. HAANet outperforms other datasets in terms of accuracy.
