Abstract
COVID-19 is a highly contagious respiratory infection caused by the SARS-CoV-2 virus. The infected lung epithelial cells secrete a group of chemokines and cytokines, which triggers harmful cytokine storms and hyper-thrombotic responses. Recent studies have proposed that viral-induced senescence is responsible for cytokine release and inflammation in COVID-19 patients. However, it is unknown whether cellular senescence is commonly triggered after viral infection and how inflammation and thrombosis, hyper-activated in these patients, are functionally connected. To address these questions, we conducted a bioinformatics-based meta-analysis using single-cell and bulk RNA sequencing datasets obtained from human patient studies, animal models, and cell lines infected with SARS-CoV-2 and other respiratory viruses. We found that the senescence phenotype is robustly upregulated in most SARS-CoV-2-infected patients, especially in the infected lung epithelial cells. Notably, the upregulation of Tissue factor (F3), a key initiator of the extrinsic blood coagulation pathway, occurs concurrently with the upregulation of the senescence-associated secretory phenotype (SASP) factors. Furthermore, F3 levels are positively correlated with the senescence and hyper-coagulation gene signatures in COVID-19 patients. Together, these data demonstrate the prevalence of senescence in respiratory viral infection and suggest F3 as a critical link between inflammation, thrombosis, and senescence in these disease states.

Abstract
Radiometal-based theranostics or theragnostics, first used in the early 2000s, is the combined application of diagnostic and therapeutic agents that target the same molecule, and represents a considerable advancement in nuclear medicine. One of the promising fields related to theranostics is radioligand therapy. For instance, the concepts of targeting the prostate-specific membrane antigen (PSMA) for imaging and therapy in prostate cancer, or somatostatin receptor targeted imaging and therapy in neuroendocrine tumors (NETs) are part of the field of theranostics. Combining targeted imaging and therapy can improve prognostication, therapeutic decision-making, and monitoring of the therapy.

Abstract
Protease inhibitors (PIs) are ubiquitous regulatory proteins present in all kingdoms. They play crucial tasks in controlling biological processes directed by proteases which, if not tightly regulated, can damage the host organism. PIs can be classified according to their targeted proteases or their mechanism of action. The functions of many PIs have now been characterized and are showing clinical relevance for the treatment of human diseases such as arthritis, hepatitis, cancer, AIDS, and cardiovascular diseases, amongst others. Other PIs have potential use in agriculture as insecticides, anti-fungal, and antibacterial agents. PIs from tick salivary glands are special due to their pharmacological properties and their high specificity, selectivity, and affinity to their target proteases at the tick-host interface. In this review, we discuss the structure and function of PIs in general and those PI superfamilies abundant in tick salivary glands to illustrate their possible practical applications. In doing so, we describe tick salivary PIs that are showing promise as drug candidates, highlighting the most promising ones tested in vivo and which are now progressing to preclinical and clinical trials.
