Summary: Antimicrobial peptides are important molecules in the organism's defense system. They can modulate the immune system and recognize molecules present in pathogens. Overstimulation of TLR4 can lead to uncontrolled inflammatory responses, which can be counteracted by antimicrobial peptides.

Summary: Exendin-4 was effective in inhibiting cocaine-induced CPP, facilitating the extinction of cocaine-associated reward, and attenuating reinstatement of cocaine-induced behavior. These effects may be attributed to the inhibition of TLR4, TNF-alpha, and IL-1 beta expression.

Summary: Accumulating evidence suggests that alcohol overconsumption is associated with insulin resistance, and this study investigated the role of hepatocyte toll-like receptor 4 (TLR4) in alcohol-induced insulin resistance. The findings indicate that hepatocyte TLR4 is both required and sufficient for the development of insulin resistance caused by alcohol overconsumption.

Summary: This review discusses TLR4 inhibitors that can bind directly to TLR4 or the TLR4/MD2 complex, as well as compounds that can downregulate the expression of TLR4. The involvement of specific residues in the binding of antagonistic ligands to the TLR4/MD2 complex provides useful information for structure-based TLR4 inhibitor design.

Summary: Doxorubicin (Dox) is commonly used chemotherapeutic drug, but its cardiotoxicity reduces its therapeutic efficacy. Dox-induced cardiac inflammation is considered as one of the underlying mechanisms involved in Dox-induced cardiotoxicity. Understanding the role of the Toll-like receptor 4 (TLR4) signaling pathway in Dox-induced cardiac inflammation might be beneficial for developing potential therapeutic strategies.

Summary: Acute kidney injury (AKI) is a common and devastating condition with no effective pharmacological treatment. Toll-like receptor 4 (TLR4) and its ligands play a crucial role in the pathogenesis of AKI by mediating inflammatory responses. Excessive activation of TLR4 can lead to chronic inflammation. This review discusses the role of TLR4 in ischemic/reperfusion-induced AKI and sepsis-associated AKI, as well as its potential signaling patterns in kidney injury.

Summary: Encapsulation of pancreatic islets in alginate-microcapsules can reduce or avoid the use of lifelong immunosuppressive drugs to prevent rejection. However, long-term graft function is limited by host tissue responses, including inflammatory responses to biomaterials and islet-derived DAMPs. A novel strategy using immunomodulatory polymer pectin with varying degrees of methyl-esterification has been developed to reduce these host tissue responses by attenuating activation of specific pro-inflammatory immune receptors locally at the transplantation site.

Summary: The blue-green alga Spirulina platensis contains phycocyanins, including C-phycocyanin (C-PC), which has hepatoprotective, nephroprotective, antioxidant, and anticancer effects. This study investigated the immunomodulatory effects of C-PC in microglia cultures and found that it upregulates the expression and release of IL-1 beta and TNF-alpha, while also promoting the nuclear translocation of the NF-kappa B transcription factor. Additionally, the study suggests that the immunoregulatory function of C-PC may involve the activation of Toll-like receptor 4 (TLR4).

Summary: This study retrospectively analyzed patient data from two databases at two high-volume bariatric centers to identify predictors of early postoperative complications after RRYGB. The results showed that male sex and ASA score > 2 were independent predictors of early postoperative complications after RRYGB.

Summary: Pressurised intraperitoneal aerosol chemotherapy (PIPAC) is a laparoscopic procedure aiming to improve local efficacy and minimize systemic side effects. The Nab-PIPAC trial is evaluating the safety and tolerability of nab-paclitaxel and cisplatin administered intraperitoneally in patients with gastric, pancreatic, or ovarian cancer. The study involves sequential intraperitoneal laparoscopic administration of nab-paclitaxel and cisplatin at escalating doses to determine the maximum tolerated dose.

Summary: After a pause caused by the COVID-19 pandemic, xenotransplantation literature updates are now restarting. Recent clinical cases and increased interest in the field have prompted the decision to reinstate this section. Pig-to-human xenotransplantation presents unique challenges that will be given specific attention. This issue aims to cover the gap and include the most relevant publications from March 2021 to March 2023.

Summary: Gastrointestinal cancer surgery is the primary treatment for gastrointestinal cancers. Prehabilitation before surgery aims to optimize the patient's condition and improve postoperative recovery. This review summarizes the latest evidence of preoperative prehabilitation on postoperative outcomes and discusses potential therapeutic targets. Preoperative interventions combining nutrition and physical activity show improvements in physical performance and quality of life in patients with esophagogastric and colorectal cancers, but no benefits in postoperative complications and mortality. Further studies are needed to confirm these findings and identify patients who will benefit from prehabilitation.

Summary: Parents of children with autism spectrum disorders (ASD) experience higher levels of stress than parents of typically-developing (TD) children, due to differences in their children's emotional functioning. The COVID-19 pandemic exacerbated the cognitive and practical demands on vulnerable populations and their families. Factors relating to the child's emotional characteristics and COVID-19 stressful events had different influences on parenting stress in the ASD and TD groups.

Summary: ICI therapy has improved the management of HCC patients and made liver transplantation possible for some of them. However, acute rejection after ICI therapy challenges its safety in transplant settings. A three-month washout period is desirable to reduce the risk of acute rejection, and the use of ICIs after liver transplantation should be avoided whenever possible.

Summary: The aim of this study was to determine the incidence of diverticulitis recurrence after sigmoid colectomy for diverticular disease. A total of 953 patients who underwent sigmoid colectomy were included in the study, with a mean follow-up of 4.8 years. During this period, 10 patients (1.1%) developed recurrent diverticulitis. The literature review revealed heterogeneity in the reported incidences of diverticulitis recurrence after sigmoid colectomy.
