Walnut-Derived Peptide Improves Cognitive Impairment in Colitis Mice Induced by Dextran Sodium Sulfate via the Microbiota–Gut–Brain Axis (MGBA)

Article

Author: Qi, Yuan ; Wang, Ji ; Liu, Xiaoting ; Leng, Yue ; Wang, Xuehang ; Min, Weihong ; Wang, Xiyan ; Wu, Dan ; Zhang, Yaoxin

In this study, we investigated the protective mechanism of walnut-derived peptide LPLLR (LP-5) against cognitive impairment induced in a dextran sodium sulfate (DSS)-induced colitis mouse model, with emphasis on the microbiota-gut-brain axis (MGBA). The results revealed that LP-5 could improve the learning ability and memory of mice with cognitive impairment and mitigate colitis symptoms, including weight loss, bloody stools, colon shortening, and histopathological changes. Additionally, LP-5 protected the integrity of the intestinal barrier by promoting the expression of tight junction proteins (TJs) while attenuating colonic inflammation by suppressing proinflammatory cytokine and epithelial cell apoptosis. Western blotting indicated that LP-5 treatment suppressed the inflammatory NF-κB/MLCK/MLC signaling pathway activity. Furthermore, LP-5 ameliorated hippocampal neuron damage and protected blood-brain barrier (BBB) integrity by downregulating microglia marker protein Iba-1, increasing TJ protein expression, and restoring the deterioration of synaptic proteins. Importantly, 16S rRNA sequencing results indicated that LP-5 reshaped the abundance of a wide range of gut microbiota at the phylum and genus levels, with increased Prevotella and Akkermansia associated with tryptophan (TRP), 5-hydroxytryptamine (5-HT), and 5-hydroxyindoleacetic acid (5-HIAA). These findings suggest that LP-5 could maintain intestinal barrier and BBB integrity, reverse gut dysbiosis, and improve learning and memory ability in colitis mice, providing novel insights into alterations of gut microbes in colitis and a potential new mechanism by which it causes cognitive impairment.

Author: Zheng, Meng ; Peng, Hengying ; Wang, Jin ; Liu, Jihua ; Li, Shanshan ; Dai, Wenling ; Ma, Bin

Managing patients with refractory inflammatory bowel diseases (IBD) is a common clinical challenge. Galli Gigeriae Endothelium Corneum (GGEC), a chicken by-product, has been used for centuries in Asian countries as a functional food and supplement for the treatment of gastrointestinal disorders. In this study, a novel peptide (LNLYP, LP-5) with gastrointestinal stability that can enhance the intestinal barrier function that was first identified in GGEC. Our work demonstrated that aryl hydrocarbon receptor (AhR) activation by LP-5 could inhibit the Src kinase to increase tight junction protein levels and down-regulate the expression of inflammatory cytokines to protect the intestinal barrier and finally alleviate dextran sulfate sodium (DSS)-induced colitis. This study revealed that LP-5 had the potential to develop into a therapeutic agent for the treatment of colitis and provided new high-valued utilization of GGEC.

Iodothyronine 5′-Deiodination in Rats Fed Low Protein Diets: Lack of Correlation with Energy Balance

Q2 · MEDICINE

Article

Author: F B Hillgartner ; D R Romsos

Rats fed low protein diets often exhibit an elevation in adaptive thermogenesis that may result in part from activation of thyroid hormone action at the level of peripheral deiodination of thyroxine (T4) to 3,5,3'-triiodothyronine (T3). This possibility was examined by comparing the kinetic parameters of iodothyronine 5'-deiodination in hepatic and renal microsomes and the efficiency of energy retention in weanling rats fed diets containing 5% (LP-5), 8% (LP-8) or 22% (NP) casein. Energy balance measurements revealed that efficiency of energy retention was reduced in rats fed LP-5, whereas no significant change in adaptive thermogenesis was observed in rats fed LP-8. In the LP-5 group the maximal activity of hepatic 5'-deiodinase per milligram of microsomal protein was not different from that of the NP group; however, the Vmax of the renal enzyme was 21% higher. In both tissues, the Km of the reaction was not affected by dietary treatment. Hepatic and renal 5'-deiodination in rats fed LP-8 was similar to that in rats fed LP-5. When compared to corresponding NP controls, each of the low protein dietary groups (LP-5, LP-8) had a higher serum total T3 concentration, whereas serum free T3 and total T4 concentrations were unaffected by the dietary treatments. The findings demonstrate that iodothyronine 5'-deiodination and circulating thyroid hormone concentrations vary in a similar manner in LP-5 and LP-8 animals even though these two groups exhibit different responses in energy efficiency relative to NP controls.(ABSTRACT TRUNCATED AT 250 WORDS)

("LongBio" or the "Company"), a Phase III-stage biotech company focused on the R&D of innovative antibody and fusion protein drugs for allergies and complement-mediated diseases, announced the completion of its Series B2 financing round, raising tens of millions of RMB. The round was led by Qiming Venture Partners, with continued support from existing investors. The funds will primarily be used to advance late-stage clinical studies in the company's pipeline, strengthen team capabilities, and bolster working capital. Leveraging its proprietary technology platform, LongBio has developed a range of innovative biologics with independent intellectual property rights. LP-003, a best-in-class, high-affinity anti-IgE antibody, has demonstrated the potential for superior efficacy, lower dosing, longer dosing intervals, and greater cost-effectiveness. Existing data indicates that: LP-003 can extend the dosing frequency of current drugs targeting the same target from once every 2-4 weeks to once every 3-6 months. 100 mg of LP-003 showed comparable efficacy to 300 mg of omalizumab. Subgroup analysis in Phase II study further revealed that LP-003 may offer superior efficacy compared to omalizumab under similar pollen density conditions. LongBio has also initiated clinical studies in China for LP-003 in various other indications, including chronic spontaneous urticaria (CSU), asthma, and food allergy. The company aims to present the topline results of the LP-003 Phase II study for CSU, using omalizumab as a positive control, at the 2025 American Academy of Allergy, Asthma & Immunology (AAAAI) meeting in San Diego, US, in February 2025.

Pre-clinical result of LP-005, a novel bi-functional complement antibody-fusion protein was unveiled by LongBio at WCN2024

BUENOS AIRES, Argentina, April 15, 2024 /PRNewswire/ -- LongBio Pharma (Suzhou) Co., Ltd. (referred to as "LongBio"), a leading biotech company dedicated to developing innovative protein treatments for nephrology, allergy, respiratory, hematology, ophthalmology, and other autoimmune and rare diseases, proudly announced the release of pre-clinical data of LP-005, a novel bi-functional complement antibody-fusion protein, at the 2024 World Congress of Nephrology (WCN24) held by International Society of Nephrology (ISN). The poster titled "Bi-functional C5 antibody-fusion protein (LP-005) with potential best-in-class bioactivity for complement inhibition" was presented by LongBio during the conference. Date and Time: April 15, 2024, at 17:45 pm (UTC -3) Location : Exhibition Hall and Main Foyer Poster Number: MON-100 Methods: Eculizumab, POT-4 (also known as APL-1) was purchased from vendors. The sequences of Ravulizumab, Crovalimab, Pozelimab, Narsoplimab and Ab-fH were obtained from INN and made in-house with LP-005, LP-005C. CP, AP, LP and C3b deposition assays with head-to-head comparison were conducted. Monkey PK/PD assay of LP-005C and Ab-fH was also conducted. Results: LP-005 shows the most potent inhibition in CP, AP and LP compared to Eculizumab, Ravulizumab, Crovalimab, Pozelimab and Narsoplimab. In addition, it also has the most efficient inhibition in C3b assay compared to Antibody-fH fusion and POT-4 (APL-1). The monkey PK/PD study indicates that when fusing to the same C5 antibody, LongBio's unique inhibitor (inCibitorTM) shows a better PK/PD profile compared to the natural fH 1-5 fragment. LP-005 is a novel bifunctional complement antibody fusion protein targeting both C3 and C5, with better bioactivity in CP, AP, LP and C3b deposition assays. Meanwhile, LP-005 is engineered to optimize surface charge (PI) and FcRn binding, making it first Q4W bi-functional complement inhibitor all over the world. With all these advantages above, LP-005 has the potential to be a best-in-class drug candidate with excellent and full complement inhibitory activity and will be explored in complement mediated disorders.
