The intracellular bacterial pathogen Brucella is capable of long-term persistence within the host, causing chronic infections that affect livestock and wildlife. Brucella's virulence is significantly influenced by the type IV secretion system (T4SS), a complex of 12 protein components dictated by the VirB operon. The function of the T4SS is carried out by the 15 effector proteins it secretes. Important signaling pathways in host cells are manipulated by effector proteins, thereby inducing host immune responses, promoting Brucella survival and replication, and contributing to persistent infection. Within the confines of this article, we investigate the intracellular circulation of cells infected by Brucella, and the part played by Brucella VirB T4SS in modulating inflammatory responses and diminishing host immune responses during infection. Importantly, the key mechanisms these 15 effector proteins use to evade the host's immune system during Brucella infection are investigated. Sustained survival of Brucella within host cells hinges upon the actions of VceC and VceA, which influence autophagy and apoptosis. BtpB, alongside BtpA, plays a critical role in the activation of dendritic cells, inducing inflammatory processes and impacting host immune responses during infection. Analyzing Brucella T4SS effector proteins and their role in immune responses, this paper provides a theoretical foundation for comprehending bacterial hijacking of host cell signaling. This understanding advances the development of improved vaccines and treatments for Brucella.

Discoidin domain receptors-1 (DDR1)'s potential role and underlying mechanisms during liver fibrogenesis were examined in this study.
From the mice, the respective blood and liver specimens were collected. In vitro experiments utilized human normal hepatocyte (LO2 cell line) and human hepatoma (HepG2 cell line) cells, which were genetically modified by lentivirus transfection to display either overexpressed DDR1 (DDR1-OE) or DDR1 knockdown (DDR1-KD). Collagen-treated, stably transfected cells' conditioned medium was used to cultivate human LX2 hepatic stellate cells. The collection of cells and supernatants was essential for molecular and biochemical analyses.
Hepatocytes from carbon tetrachloride (CCL4)-induced fibrotic livers in wild-type (WT) mice demonstrated an elevation of DDR1 expression, differing markedly from hepatocytes in normal livers. In CCL4-treated DDR1 knockout (DDR1-KO) mice, relief of liver fibrosis and a reduction in hepatic stellate cell (HSC) activation were observed compared to CCL4-treated wild-type (WT) mice. LX2 cells, which were cultured in the culture medium derived from LO2 DDR1-overexpressing cells, exhibited a rise in smooth muscle actin (SMA) and type I collagen (COL1) expression and an increase in cell proliferation. Concurrent with these observations, cell proliferation and the levels of SMA and COL1 proteins were decreased in LX2 cells grown in conditioned medium from HepG2 DDR1-knockdown cells. Furthermore, IL6, TNF, and TGF1, present in the conditioned medium of DDR1-overexpressing cells, seemed to stimulate LX2 cell activation and proliferation, a process controlled by the NF-κB and Akt signaling pathways.
DDR1's action within hepatocytes appears to instigate HSC activation and proliferation, with paracrine factors like IL6, TNF, and TGF1 potentially being the underlying mediators, resulting from DDR1's activation of the NF-κB and Akt pathways. Our research points to collagen-receptor DDR1 as a promising therapeutic option for managing hepatic fibrosis.
Hepatocyte DDR1 activity was linked to increased HSC activation and proliferation. Paracrine factors, including IL6, TNF, and TGF1, potentially induced by DDR1 and consequently activating NF-κB and Akt pathways, might explain the underlying mechanism. Our analysis of the data reveals a potential therapeutic application of the collagen-receptor DDR1 in addressing hepatic fibrosis.
