International Journal of Cancer, Volume 159, Issue 8, Page 1873-1883, 15 October 2026.ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers due to its asymptomatic progression, late‐stage diagnosis, and treatment resistance. Efforts in early detection have centered on identifying imaging features and liquid biopsy biomarkers capable of detecting PDAC and its high‐grade precursors before clinical symptoms ...

Association between Lewis blood group and symptomatic cholera infection.
, 2013 Lewis blood group phenotype was determined using dot blot immunoassay procedure from saliva samples. The chi-square test was used to compare the distribution of Lewis blood types in different populations, i.e. patients, contacts and healthy controls.

, 1990 We examined the distribution of blood group-related antigens using an indirect immunoperoxidase method with monoclonal antibodies (MAb) directed to A, B, H, Lewis a (Lea), Lewis b (Leb), Lewis x (Lex), and Lewis y (Ley) antigens and Type 1 precursor ...

Role of the Lewis and ABO Blood Group Antigens in Helicobacter pylori Infection.
The Malaysian journal of medical sciences : MJMS, 2013 Helicobacter pylori infection is a major risk factor for chronic gastritis and gastric cancer. Some findings show increased frequencies of these diseases in individuals with type O blood and in secretors (expressing Le(b) antigen), but other studies have not found any relationship between blood groups and this infection. Given that H.

Blood group antigen expression is involved in C. albicans interaction with buccal epithelial cells
, 2017 Human blood group polymorphisms are known to be determined by the expression of A, B or H antigens and the Lewis antigens. Protection against microbial infections has been associated with inheritance of polymorphisms in genes encoding and regulating the ...

Helicobacter pylori adhesion to gastric epithelial cells is mediated by glycan receptors
Brazilian Journal of Medical and Biological Research, 2010 Helicobacter pylori adhesion to gastric epithelial cells constitutes a key step in the establishment of a successful infection of the gastric mucosa. The high representation of outer membrane proteins in the bacterial genome suggests the relevance of ...

Changes of the expression of Lewis blood group antigens in glycoproteins of renal cancer tissues [PDF]
Acta Biochimica Polonica, 2013 Sialic acid and sialyl Lewisa/x are found on N- and O-glycans of many human malignant cells. Carbohydrate antigens can be used as tumor markers, and an increase of their levels in cancer cells is associated with tumor progression.

Structural Constraints on Human Norovirus Binding to Histo-Blood Group Antigens
, 2016 Human norovirus interacts with the polymorphic human histo-blood group antigens (HBGAs), and this interaction is thought to be important for infection. The genogroup II genotype 4 (GII.4) noroviruses are the dominant cluster, evolve every other year, and
