Intestinal estrogen receptor beta modulates the murine colon tumor immune microenvironment

Article

作者: Kutter, Claudia ; Gallardo-Dodd, Carlos J ; Williams, Cecilia ; Chen, Baizhen ; Birgersson, Madeleine ; Hases, Linnea ; Holm, Matilda ; Archer, Amena ; Stepanauskaitė, Lina

Chronic inflammation contributes to the development of colorectal cancer, partly through its regulation of the microenvironment and antitumor immunity. Interestingly, women have a lower incidence of colorectal cancer, and estrogen treatment has been shown to reduce the occurrence of colorectal tumors. While intestinal estrogen receptor beta (ERβ, Esr2) can protect against colitis and colitis-induced cancer in mice, its role in shaping the tumor microenvironment remains unknown. In this study, we performed RNA sequencing to analyze the transcriptome of colonic epithelia and tumors from azoxymethane/dextran sulfate sodium-treated wild-type and intestinal ERβ knockout (ERβKO^Vil) mice and vehicle-treated controls. This revealed significant differences in gene expression and enriched biological processes influenced by sex and genotype, with immune-related responses being overrepresented. Deconvolution supported differential immune cell abundance and immunostaining showed that tumors from ERβKO^Vil mice displayed significantly increased macrophage infiltration, decreased T cell infiltration, and impaired natural killer cell infiltration. Further, ERβ mRNA levels in clinical colorectal tumors correlated with immune signaling profiles and better survival. Our findings indicate that intestinal ERβ promotes an antitumor microenvironment and could potentially affect the effectiveness of immunotherapy. These insights highlight the importance of ERβ in modulating antitumor immunity and underscore its therapeutic potential in colorectal cancer.

Studies have shown that dysregulation of intestinal microbial structure and co-metabolic imbalance caused by diet and other factors play important role in MASLD and IBD. However, it is unclear how host-microbial interactions differ in the two diseases, and what potential impact they have on accelerating disease progression. Our study aims to find the disease characteristics in MASLD, IBD and their complication from the perspective of host-microbial metabolism. In our study, mouse models of MASLD, IBD, and MASLD-IBD induced by high-fat diet and dextran sulfate sodium. Detecting the pathological changes of colon and liver. Using 16s rRNA to screen out specific micro-flora, and UPLC-MS to monitor the changes of metabolites in feces. The micro-flora-metabolite co-expression network was constructed by Cytoscape software. The result showed that MASLD-IBD mice aggravate intestinal barrier damage, hepatic steatosis and fibrosis, immune inflammation and other pathological changes. In MASLD-IBD mice, the structural change of gut micro-flora is similar to IBD mice, which significantly reduced the abundance of Actinobacteriota, Desulfobacterota while increasing the abundance of Proteobacteria, and the metabolic disorder include nine metabolic pathways, such as tryptophan, bile acids and short-chain fatty acids, is similar to MASLD mice. Their co-expression network indicates that different specific micro-flora are closely related to the metabolic disorder and disease symptoms of MASLD-IBD mice. Analyzing the relationship between intestinal microbial dysregulation and hoetic co-metabolic imbalance is helpful to understand the mechanism of MASLD and IBD comorbidity, which suggesting that combined liver-gut therapy may be a new method for the treatment of MASLD-IBD complication.

Molecular Ultrasound Imaging With Clinically Translatable cRGD-Coated Microbubbles to Assess αvβ3-Integrin Expression in Inflammatory Bowel Disease

Article

作者: Kiessling, Fabian ; Kozcera, Patrick ; Rix, Anne ; Shi, Yang ; von Stillfried, Saskia ; Qi, Jinwei ; Chen, Junlin

Objectives:

Inflammatory bowel disease (IBD) subdivides into Crohn disease (CD) and ulcerative colitis (UC), and is characterized by unpredictable periods of inflammation and results in significant patient suffering and even death. Conventional diagnostic methods, for example, colonoscopy, computed tomography, or magnetic resonance imaging, have limitations such as invasiveness, patient discomfort, and limited sensitivity and accuracy. Therefore, we propose ultrasound molecular imaging (USMI) to detect and characterize IBD. First, we evaluated integrin-αvβ3 as a biomarker of IBD in human samples and then used clinically translatable cyclic Arg-Gly-Asp-D-Phe-Lys (cRGDfK)–coupled poly(butyl)cyanoacrylate microbubbles (cRGD-MB) to assess IBD in mice.

Materials and Methods:

Vascular integrin-αvβ3 expression in human colon tissue samples (healthy, CD and UC, n = 10 per group) was analyzed by immunofluorescence staining. In mice, acute colitis was induced by administration of 4% dextran sodium sulfate in drinking water for 5 days. On day 7, USMI with cRGD-MB was performed in colitis (n = 6) and healthy (n = 5) mice. The signal of bound cRGD-MB was assessed by the destruction-replenishment method. Ex vivo analysis of mouse colon tissue was performed to assess the degree of colitis by hematoxylin-eosin staining and the vascular expression of integrin-αv by immunofluorescence.

Results:

Human samples showed a significantly higher vascular integrin-αvβ3 expression in CD and UC tissue, when compared with healthy samples (P < 0.005). In mice, a higher binding of cRGD-MB to inflamed colon was detected by USMI compared with healthy controls (P < 0.005). Immunofluorescence staining confirmed these findings, showing stronger integrin-αv expression in acute colitis, with a good correlation between USMI signal intensity and integrin-αv expression (r = 0.8, P = 0.0016).

Conclusions:

Integrin-αvβ3 on vessels is a suitable marker for IBD. USMI using cRGD-MB accurately detects this marker and correlates well with histology. These encouraging results support clinical translation of this imaging method as a noninvasive and cost-effective monitoring tool.

TikoMed's ILB® inhibits cell infection by coronaviruses and modulates reactive cytokine release from microglia in vitro

Adds further support for its broad-spectrum mechanism of action following other recent TBI, ALS and tropical virus studies VIKEN, Sweden, Sept. 13, 2022 /PRNewswire/ -- TikoMed today announced the inclusion in bioRxiv* of an in vitro study evaluating the ability of the company's lead drug candidate ILB® to: inhibit infection of human cells by the NL63 coronavirus assessed by immunofluorescence of viral particles; and directly block the interaction of the SARS-CoV-2 viral spike protein with the ACE2 receptor; and modulate the downstream consequences of viral infection including the reactive cytokine release from human microglia induced by various SARS-CoV-2 variant spike proteins. The study shows that ILB® blocked ACE2:spike protein interaction and inhibited coronaviral infection. ILB® also attenuated the omicron-induced release of pro-inflammatory cytokines, including TNFa, from human microglia, indicating control of post-viral neuroinflammation. "This work extends our findings of ILB®'s antiviral impact upon flavivirus infections to now include coronavirus. Furthermore, we are excited to have uncovered a potential molecular mechanism for these findings by showing that ILB® inhibited SARS-CoV-2 spike protein interacting with ACE2, the key docking site for SARS-CoV-2 to gain entry to human cells," said Professor Ann Logan PhD (Professor of Regenerative Medicine & CSO, Axolotl Ltd). Professor Nicholas Barnes PhD PBPhS (Professor of Pharmacology & CEO, Celentyx Ltd) also commented: "In pathological post-viral fatigue syndromes such as long COVID, a key brain cell called microglia appear overactive and promote the associated neuroinflammation. This data showed that activated microglia are calmed by ILB® in vitro and suggests ILB® has the potential to inhibit neuroinflammation and hence improve symptoms of patients with conditions such as long COVID." TikoMed recently announced the publication of a peer-reviewed article on the mode of action of ILB®. In multiple preclinical and clinical studies across a variety of neuroinflammation-driven diseases.

TikoMed's drug candidate ILB® inhibited infection of human cells by Dengue, Zika and Yellow Fever viruses in vitro, providing further support for its broad spectrum mechanism of action

VIKEN, Sweden, Sept. 7, 2022 /PRNewswire/ -- TikoMed today announced the inclusion in bioRxiv* of an in vitro study examining the ability of the company's lead drug candidate ILB® to inhibit infection of human cells by four serotypes of Dengue virus (DENV1-4), two strains of Zika virus (African and Asian) and Yellow Fever virus (vaccine strain YF17D) assessed by immunofluorescence of viral particles. In the study, ILB® potently inhibited infection by all the strains of Dengue, Zika and Yellow Fever virus in a concentration-dependent manner with IC50 for ILB® ranging from 31 to 343 μg/ml. Professor Nicholas Barnes PhD PBPhS (Professor of Pharmacology & CEO, Celentyx Ltd, and one of the world's most highly cited researchers ) commented: "It is well recognised that infection by flaviviruses like Dengue, Zika and Yellow Fever virus can lead to catastrophic life-threatening conditions. This emphasises the clinical need for safe and effective medicines to treat these infections. What I find particularly exciting about these results is the effects observed at ILB® concentrations that have been achieved in humans following doses that have been well tolerated. These findings offer hope to the millions of patients that continue to be devastated by flavivirus infections." TikoMed recently announced the publication of a peer-reviewed, scientific article on the mode of action of ILB®. In multiple preclinical and clinical studies across a variety of neuroinflammation-driven diseases. ILB® both mobilized and modulated naturally occurring tissue repair mechanisms, released heparin-binding growth factors, and restored cellular homeostasis and function. "These results provide further evidence of the anti-viral potential and unique broad spectrum mechanism of action of TikoMed's ILB® drug platform. We have already initiated clinical development programs for Amyotrophic Lateral Sclerosis (ALS), Traumatic Brain Injury (TBI) and islet cell transplantation and plan to consider additional evaluation in other diseases," said Anders Kristensson, CEO of TikoMed. *bioRxiv is a free online archive and distribution service for unpublished preprints in the life sciences.

About flaviviruses Flaviviruses are responsible for the most abundant arboviral diseases of humans in terms of geographical distribution, morbidity and mortality; at least 2.5 billion people are at risk with, for example, an estimated 100-400 million Dengue infections a year. However, for infections by Dengue, Zika or Yellow Fever virus there are no effective anti-infective drug treatments nor for Dengue or Zika virus a safe effective vaccine and prevention at present focusses on vector (mosquito) control. Whilst symptoms from Dengue, Zika and Yellow Fever virus infection may be mild for some, they are very serious and life threatening for others. For instance, severe Dengue is a leading cause of hospitalisation and death among children and adults in Asian and Latin American countries. Likewise, Zika infection can have catastrophic consequences for pregnant women following the passing of the virus to their foetus with arising miscarriage or birth defects including microcephaly that can be fatal.
