The Relationship

As we known, Caspase 2 is widely studied for its apoptosis regulatory function in mammals. However, despite the fundamental role of apoptosis during the anti-viral immune response, the relationship between Caspase 2 and virus infection has not been extensively explored in invertebrates, whether miRNAs are involved in this process also remains unclear. To address this issue, the miRNA-mediated regulation of Caspase 2 in mud crab Scylla paramamosain was characterized in this study. The results suggested that Sp-Caspase 2 could suppress white spot syndrome virus (WSSV) infection via apoptosis induction. The further data showed that Caspase 2 was directly targeted by miR-2 in mud crab. Silencing or overexpression of miR-2 could affect apoptosis and WSSV replication through regulating the expression level of Caspase 2. Taken together, all these results demonstrated the crucial role of miR-2-Caspase 2 pathway in the innate immunity of mud crab and revealed a novel mechanism during anti-viral immune response in marine invertebrates.

Vitamin A (retinol) is one of the key elements for regulating the immune response and controls the division and differentiation of epithelial cells of the mucous membranes of the bronchopulmonary system, gastrointestinal tract, urinary tract, eyes, etc. Its significance in the context of the COVID‑19 pandemic is difficult to overestimate. However, a number of studies conducted in the past have associated the additional intake of vitamin A with an increased risk of developing cancer, as a result of which vitamin A was practically excluded from therapeutic practice in developed countries. Our review highlights the role of vitamin A in maintaining human health and the latest data on its effect on the development mechanisms of somatic pathology.

Response Evaluation Criteria

Response evaluation criteria in solid tumors (RECIST) are a method used to evaluate and document the response to cancer treatment in solid tumors. The availability of a new class of immuneoncology drugs has resulted in the need to modify RECIST criteria methodology. The first leadership immuno-oncology network (LION) master course brought together experts in oncology and immuno-oncology. Six questions were put to the experts and their opinion, supporting evidence, and experience were discussed to arrive at a practical consensus recommendation. n this nascent field, the availability of a practical consensus recommendation developed by experts in the field is of immense value to the community oncologist and other health-care consultants.

Background:: Ferritin is a molecule that plays many roles being the storage for iron, signalling molecule, and modulator of the immune response. Methods:: Different electronic databases were searched in a non-systematic way to find out the literature of interest. Results:: The level of ferritin rises in many inflammatory conditions including autoimmune disorders. However, in four inflammatory diseases (i.e., adult-onset Still’s diseases, macrophage activation syndrome, catastrophic antiphospholipid syndrome, and sepsis), high levels of ferritin are observed suggesting it as a remarkable biomarker and pathological involvement in these diseases. Acting as an acute phase reactant, ferritin is also involved in the cytokine-associated modulator of the immune response as well as a regulator of cytokine synthesis and release which are responsible for the inflammatory storm. Conclusion:: This review article presents updated information on the role of ferritin in inflammatory and autoimmune diseases with an emphasis on hyperferritinaemic syndrome.

Interstitial lung disease, a term for a group of disorders, causes lung fibrosis, is mostly refractory to treatments and has a high death rate. After diagnosis the survival is up to 3 years but in some cases the patients live much longer. It involves a heterogenous group of lung diseases that exhibit progressive and irreversible destruction of the lung due to the formation of scars. This results in lung malfunction, disruption of gas exchange, and eventual death because of respiratory failure. The etiology of lung fibrosis is mostly unknown with a few exceptions. The major characteristics of the disease are comprised of injury of epithelial type II cells, increased apoptosis, chronic inflammation, monocytic and lymphocytic infiltration, accumulation of myofibroblasts, and inability to repair damaged tissue properly. These events result in abnormal collagen deposition and scarring. The inflammation process is mild, and the disease is primarily fibrotic driven. Immunosuppressants do not treat the disease but the evidence is evolving that both innate and acquired immune responses a well as the cytokines contribute to at least early progression of the disease. Furthermore, mediators of inflammation including cytokines are involved throughout the process of lung fibrosis. The diverse clinical outcome of the disease is due to different pattern of inflammatory markers. Nonetheless, the development of novel therapeutic strategies requires better understanding of the role of the immune response. This review highlights the role of the immune response in interstitial lung disease and considers the therapeutic strategies based on these observations. For this review several literature data sources were used to assess the role of the immune response in interstitial lung disease and to evaluate the possible therapeutic strategies for the disease.

Transglutaminases TG2 and FXIII-A have recently been linked to adipose tissue biology and obesity, however, human studies for TG family members in adipocytes have not been conducted. In this study, we investigated the association of TGM family members to acquired weight gain in a rare set of monozygotic (MZ) twins discordant for body weight, i.e., heavy–lean twin pairs. We report that F13A1 is the only TGM family member showing significantly altered, higher expression in adipose tissue of the heavier twin. Our previous work linked adipocyte F13A1 to increased weight, body fat mass, adipocyte size, and pro-inflammatory pathways. Here, we explored further the link of F13A1 to adipocyte size in the MZ twins via a previously conducted TWA study that was further mined for genes that specifically associate to hypertrophic adipocytes. We report that differential expression of F13A1 (ΔHeavy–Lean) associated with 47 genes which were linked via gene enrichment analysis to immune response, leucocyte and neutrophil activation, as well as cytokine response and signaling. Our work brings further support to the role of F13A1 in the human adipose tissue pathology, suggesting a role in the cascade that links hypertrophic adipocytes with inflammation.
