Influence of Host Sialic Acid Receptors Structure on the Host Specificity of Influenza Viruses

open access: yesViruses, 2022
Influenza viruses need to use sialic acid receptors to invade host cells, and the α-2,3 and α-2,6 sialic acids glycosidic bonds linking the terminal sialic acids are generally considered to be the most important factors influencing the cross-species ...

Mortality during dispersal and the cost of host-specificity in parasites: how many aphids find hosts?

open access: yes, 1998
1. For a full assessment of explanations for the evolution of host-specificity it is necessary to estimate the probability that a dispersing parasite finds a host.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Microphallus pseudopygmaeus (Digenea) infects phylogenetically distant gastropods, with signs of host-linked genetic divergence

open access: yesParasite
Host-switching between distantly related host species offers rare insight into how parasites overcome compatibility barriers and initiate evolutionary divergence.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Bjerkandera carnegieae comb. nov. ( Phanerochaetaceae , Polyporales ) a wood-decay polypore of cactus

open access: yesPlant and Fungal Systematics, 2021
Poria carnegieae was described from Arizona growing on the woody ribs of the saguaro cactus, Carnegiea gigantea , and was transferred to Ceriporiopsis due to morphological evidence.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Trematode Infection Prevalence Increases With Snail Richness: Observations From a 4‐Year Study of Snail–Trematode Interactions

open access: yesEcology and Evolution
Digenetic trematodes are valuable study organisms for exploring how biodiversity influences disease. In this study, we investigated the relationship between snail richness and trematode infection prevalence using data from a 4‐year study (2019–2022) of ...

Molecular basis of host specificity in human pathogenic bacteria

open access: yesEmerging Microbes and Infections, 2014
Pathogenic bacteria display various levels of host specificity or tropism. While many bacteria can infect a wide range of hosts, certain bacteria have strict host selectivity for humans as obligate human pathogens. Understanding the genetic and molecular
