GM-CSF acts as a pro-inflammatory cytokine and a key growth factor produced by several immune cells such as macrophages and activated T cells. In this review, we discuss recent studies that point to the crucial role of GM-CSF in the immune response against infections. Upon induction, GM-CSF activates four main signalling networks including the JAK/STAT, PI3K, MAPK, and NFκB pathways. Many of these transduction pathways such as JAK/STAT signal via proteins commonly activated with other antiviral signalling cascades, such as those induced by IFNs. GM-CSF also helps defend against respiratory infections by regulating alveolar macrophage differentiation and enhancing innate immunity in the lungs. Here, we also summarize the numerous clinical trials that have taken advantage of GM-CSF's mechanistic attributes in immunotherapy. Moreover, we discuss how GM-CSF is used as an adjuvant in vaccines and how its activity is interfered with to reduce inflammation such as in the case of COVID-19. This review brings forth the current knowledge on the antiviral actions of GM-CSF, the associated signalling cascades, and its application in immunotherapy.

Neddylation is a process of attaching neuronal precursor cell-expressed developmentally downregulated protein 8 (NEDD8) to substrates for the protein function modulation via enzymatic cascades involving NEDD8-activating enzyme (E1), NEDD8-conjugating enzyme (E2), and NEDD8 ligase (E3). Defective in cullin neddylation 1 (DCN1) serves as a co-E3 ligase, that can simultaneously bind E2 UBE2M and cullin proteins to stabilize the catalytic center of the Cullin-Ring E3 ligase (CRL) complex, thereby promoting cullin neddylation. Neddylation is reported to be activated in diverse human diseases, and inhibition of protein neddylation has been regarded as a promising anticancer therapy.

Activation of the p38 mitogen-activated protein kinase (MAPK) pathways is vital in regulating cell growth, differentiation, apoptosis, and stress response, significantly affecting tumorigenesis and cancer progression. We developed a bioinformatic technique to construct an interactome network-based molecular pathways for genes of interest and quantify their activation levels using high-throughput gene expression data. This study is focused on the p38α, p38β, p38γ, and p38δ kinases, examining their activation levels (PALs) based on transcriptomic data and their associations with survival and drug responsiveness across various cancer types.

Cell models emulating an in vitro parasitic infection can greatly improve our understanding of helminthiases. Nonetheless, it remains challenging to select an appropriate in vitro model to study molecular pathogenesis of infections by trematodes having a complex life cycle. Therefore, adequate models are in high demand.

Ethnopharmacological Relevance: Cholestatic liver injury (CLI) is a pathophysiological syndrome characterized by the accumulation of bile acids (BAs), which leads to significant hepatic dysfunction. This condition is frequently associated with disturbances in BAs homeostasis and the induction of oxidative stress. Ribes diacanthum Pall (RDP), a conventional folk medicinal plant, has been employed in Mongolia, the Inner Mongolia region of China, and other areas for the remediation of hepatic disorders.

Aluminium (Al)-induced programmed cell death (PCD) is thought to be a main cause of Al phytotoxicity. However, the underlying mechanism by which Al induces PCD in plants is unclear. In this study, we characterized the function of AhASRK1 (Aluminum Sensitive Receptor-like protein Kinase1), an Al-induced LRR-type receptor-like kinase gene.
