AI Article Synopsis
- The study examined how human neutrophils interact with the Gram-negative pathogen Yersinia pseudotuberculosis in lab settings.
- Despite existing research on how Yersinia impacts neutrophil function, there's a lack of studies on whether neutrophils can kill Yersinia.
- The findings showed that the Y. pseudotuberculosis strain IP32953 is resistant to neutrophil killing, although the bacteria were still taken up by the neutrophils.
Article Abstract
The interaction between human neutrophils and the Gram negative gastrointestinal pathogen Yersinia pseudotuberculosis was investigated in vitro. Despite the wealth of data describing how Yersinia can affect the function of neutrophils, there are no published studies describing if neutrophil cells can affect the viability of Y. pseudotuberculosis. The wild-type IP32953 strain of Y. pseudotuberculosis was found to be resistant to killing by human neutrophils. Confocal examination and flow-cytometric analysis of this interaction revealed that bacteria were taken up.

CD44 in myEloid cells is a major driver of liver inflammation and injury in alcohol-related liver disease.

Background And Aims: Alcohol-related liver disease (ALD) is one of the leading causes of severe liver disease with limited pharmacological treatments for alcohol-related steatohepatitis (ASH). CD44, a glycoprotein mainly expressed in immune cells, has been implicated in multiple inflammatory diseases but has never been studied in the ALD context. We therefore studied its contribution to ASH development in mice and its expression in ALD patients.

SUMMARY is a major human pathogen. It can cause many types of infections, in particular bacteremia, which frequently leads to infective endocarditis, osteomyelitis, sepsis, and other debilitating diseases. The development of secondary infections is based on the bacterium's ability to associate with endothelial cells lining blood vessels.

Background: Vitamin D is the focus of extensive medical research globally. Recent studies have investigated the correlation between serum 25-hydroxyvitamin D (25(OH)D) and common inflammatory markers. However, few studies have incorporated novel inflammatory markers such as the platelet-to-lymphocyte ratio (PLR), platelet-to-high density lipoprotein cholesterol ratio (PHR), systemic inflammatory index (SII), neutrophil-to-lymphocyte ratio (NLR), systemic inflammatory response (SIRI), and neutrophil-to-high-density lipoprotein cholesterol ratio (NHR).

Background: This study aimed to investigate the risk factors associated with the severity of the disease, the need for mechanical ventilation (MV) and poor prognosis in the early stages of Guillain-Barré Syndrome (GBS).
Methods: Data of children who met GBS diagnostic criteria were evaluated retrospectively. The sample was divided into three binary subgroups according to severe GBS (Hughes Functional Grading Scale [HFGS] ≥ 4 at admission), mechanical ventilation (MV) requirement, and poor prognosis (inability to walk independently, HFGS ≥ 3 after six months).

The tumor microenvironment (TME) is integral to cancer progression, impacting metastasis and treatment response. It consists of diverse cell types, extracellular matrix components, and signaling molecules that interact to promote tumor growth and therapeutic resistance. Elucidating the intricate interactions between cancer cells and the TME is crucial in understanding cancer progression and therapeutic challenges.
