Arginine depletion as a mechanism for the immune privilege of corneal allografts. [PDF]

open access: yes, 2011
The cornea is an immune privileged tissue. Since arginase has been found to modulate T-cell function by depleting arginine, we investigated the expression of arginase in the cornea and its possible role in immune privilege using a murine transplant model.

Immune checkpoint receptors: homeostatic regulators of immunity [PDF]

open access: yesHepatology International, 2018
Alcoholic liver disease (ALD) is an escalating global problem accounting for more than 3 million deaths annually. Bacterial infections are diagnosed in 25-47% of hospitalized patients with cirrhosis and represent the most important trigger for acute decompensation, multi-organ failure, septic shock and death.

Microbial-immune cross-talk and regulation of the immune system

open access: yes, 2012
We are all born germ-free. Following birth we enter into a lifelong relationship with microbes residing on our body's surfaces. The lower intestine is home to the highest microbial density in our body, which is also the highest microbial density known on

Therapeutic potential of T-cell receptor targeting the HLA-A*11:01-restricted KRASG12V neoantigen without cross-recognition of the self-antigen RAB7B in solid tumors

open access: yesJournal for ImmunoTherapy of Cancer
Background Public neoantigens, including KRAS, TP53, and PIK3CA mutations, which are shared across various tumor types, have demonstrated significant immunogenicity and offer great promise for cancer immunotherapy.

Shaping of Intestinal Microbiota in Nlrp6- and Rag2-Deficient Mice Depends on Community Structure

open access: yesCell Reports, 2017
Contradicting observations have been made regarding the relative contributions of immune sensors to shaping the microbiome, yet the reasons for these discrepancies are not fully understood.

Immune System Modulations by Products of the Gut Microbiota

open access: yes, 2020
The gut microbiota, which consists of all bacteria, viruses, fungus, and protozoa living in the intestine, and the immune system have co-evolved in a symbiotic relationship since the origin of the immune system.

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 ...

Testing the theory of immune selection in cancers that break the rules of transplantation

open access: yes, 2009
Modification of cancer cells likely to reduce their immunogenicity, including loss or down-regulation of MHC molecules, is now well documented and has become the main support for the concept of immune surveillance.

Chronic Lymphocytic Leukemia Cells Are Activated and Proliferate in Response to Specific T Helper Cells

open access: yesCell Reports, 2013
There is increasing interest in the chronic lymphocytic leukemia (CLL) microenvironment and the mechanisms that may promote CLL cell survival and proliferation.

Autocrine TGF-β1 Maintains the Stability of Foxp3+ Regulatory T Cells via IL-12Rβ2 Downregulation

open access: yesBiomolecules, 2020
Transforming growth factor beta 1 (TGF-β1) is an immunosuppresive cytokine that plays an essential role in immune homeostasis. It is well known that regulatory T (Treg) cells express TGF-β1; however, the role of autocrine TGF-β1 in the development ...
