In response to MI, the myocardium undergoes a series of wound healing events that initiate inflammation and shift to anti-inflammation before transitioning to tissue repair that culminates in scar formation to replace the region of the necrotic myocardium. The overall response to MI is determined by two major steps, the first of which is the secretion of proteases by infiltrating leukocytes to breakdown extracellular matrix (ECM) components, a necessary step to remove necrotic cardiomyocytes. The second step is the generation of new ECM that comprises the scar; and this step is governed by the cardiac fibroblasts as the major source of new ECM synthesis. The leukocyte component resides in the middle of the two-step process, contributing to both sides as the leukocytes transition from pro-inflammatory to anti-inflammatory and reparative cell phenotypes. The balance between the two steps determines the final quantity and quality of scar formed, which in turn contributes to chronic outcomes following MI, including the progression to heart failure. This review will summarize our current knowledge regarding the cardiac wound healing response to MI, primarily focused on experimental models of MI in mice.

During the early stages of the pandemic, the lack of formalized evidence-based guidelines in all aspects of patient management was a significant challenge. Coupled with a lack of effective pharmacotherapies resulted in unsatisfactory outcomes in ICU patients. The anticipated increment in ICU surge capacity was staggering, with almost every ICU worldwide being advised to increase their capacity to allow adequate care provision in response to multiple waves of the pandemic. This increase in surge capacity required advanced planning and reassessments at every stage, taking advantage of experienced gained in combination with emerging evidence. In University Hospital Southampton General Intensive Care Unit (GICU), despite the initial lack of national and international guidance, we enhanced our ICU capacity and developed local guidance on all aspects of care to address the rapid demand from the increasing COVID-19 admissions. The main element of this success was a multidisciplinary team approach intertwined with equipment and infrastructural reorganization. This narrative review provides an insight into the approach adopted by our center to manage patients with COVID-19 critical illness, exploring the initial planning process, including contingency preparations to accommodate (360% capacity increment) and adaptation of our management pathways as more evidence emerged throughout the pandemic to provide the most appropriate levels of care to our patients.

However, unexpected serious toxicities such as cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) still hamper its broad application. Clinical trials using CAR-T cells targeting specific antigens on tumor cell surface have provided valuable information about the characteristics of ICANS. With unclear mechanism of ICANS after CAR-T treatment, unremitting efforts have been devoted to further exploration. Clinical findings from patients with ICANS strongly indicated existence of overactivated peripheral immune response followed by endothelial activation-induced blood-brain barrier (BBB) dysfunction, which triggers subsequent central nervous system (CNS) inflammation and neurotoxicity. Several animal models have been built but failed to fully replicate the whole spectrum of ICANS in human. Hopefully, novel and powerful technologies like single-cell analysis may help decipher the precise cellular response within CNS from a different perspective when ICANS happens. Moreover, multidisciplinary cooperation among the subjects of immunology, hematology, and neurology will facilitate better understanding about the complex immune interaction between the peripheral, protective barriers, and CNS in ICANS. This review elaborates recent findings about ICANS after CAR-T treatment from bed to bench, and discusses the potential cellular and molecular mechanisms that may promote effective management in the future.

Conversely, EVs released from infected and/or diseased cells could be useful as markers in the detection and diagnosis of disease conditions such as cancer at their earliest most detectable, and treatable stage. A very important type of EVs, termed exosomes offer a hypothetical new paradigm in disease detection, diagnosis, and treatment. A broad range of exosome-based biomedical and therapeutic applications are now being evaluated in recent clinical trials. Exosomes are found in virtually all bodily fluids and cells and are capable of crossing tight junctions and toughly regulated boundaries such as the blood-brain barrier. Exosomes' expedition ends when they are taken up by bystander cells which corroborates the fact that they are conduits for cells releasing them. Exosomes released by diseased cells have been associated with cell-to-cell progression of diseases like viral disease, neurodegeneration, and certain cancers. Due to high discrimination in most disease conditions, exosome uptake is usually cell-specific. Lots of research evidence have revealed that infusion of exosomes derived from regenerative cells such as stem cells could impede the development of certain infections and age-related diseases by activating self-repair machinery through RNA, DNA, protein, and lipid transfer between cells in patients. They have also been demonstrated in the restoration of the circulating population of exosomes in tissues and the fluid of recipients.

Resistance to chemotherapy is a major challenge in kidney cancer treatment in the clinic. Tremendous progress has been made in identifying the molecular changes associated with chemotherapy resistance in RCC. However, the exact contribution of these molecular changes to the acquisition of chemotherapy resistance is not fully understood. In addition to genetic changes, epigenetic alterations have been shown to contribute to various pathways associated with chemotherapy resistance, such as increased cell proliferation and survival, regulation of drug influx and efflux transporters, increased DNA repair, loss of DNA-damage-dependent apoptotic potential, cellular dedifferentiation to cancer stem cell, and epithelial-mesenchymal transitions (EMT). Moreover, recent studies suggest that epigenetic aberrations that can be reversed by epigenetic therapeutics can potentially be targeted to restore chemosensitivity in chemorefractory kidney cancer.
