polysaccharide (DSPS) is the main natural compound extracted from the traditional Chinese herb . Although DSPS is well-known for its antioxidant and anti-inflammatory properties, its impact on aflatoxin B1 (AFB1)-induced damage has not been explored. This study aims to investigate the potential protective mechanisms of DSPS against AFB1-induced liver damage and immune disorders.

H9N2 is an increasing threat to global poultry production and human health. Vaccination of poultry is a key element of disease control in endemic countries, but the inactivated H9N2 vaccine needs to be used with adjuvants to compensate for its weak immunogenicity. Salvia miltiorrhiza polysaccharide (SMP) and Mn have received extensive attention because of their ability to enhance adaptive immunity and stimulate IFN-β secretion, respectively.

Protein C receptor (Procr) cells were identified as stem or progenitor cells in multiple adult tissues. However, whether mechanical stimuli fine-tune their activation and differentiation remain unknown. Here, we found rare Procr cells in the superficial layer of tibial articular cartilage and meniscus, which keep replenishing chondrocytes in postnatal knee joints.

Conventional alum adjuvants primarily induce a Th2 humoral immune response yet fail to provoke a Th1 cellular immune response. In our preceding study, we constructed a novel and biosafe nanoparticle-based adjuvant system, in which the Chinese yam polysaccharide (CYP), as the immunopotentiator, was loaded onto aluminum hydroxide nanoparticles (CYP-AlNPs). Herein, we further investigated the adjuvant activity of the CYP-AlNPs against the porcine circovirus type 2 (PCV2) vaccine.

Developing a novel and potent adjuvant with excellent biocompatibility for immune response augmentation is crucial for enhancing vaccine efficacy. Here, we prepared a stable PLGA nanoparticle by encapsulating MnCl/Salvia miltiorrhiza polysaccharide (MS-PLGA) and employed it as an adjuvant in the model antigen OVA (MS-PLGA-OVA) to elicit potent immunity. The biological experiments indicated that the MS-PLGA-OVA could effectively recruit APCs to the injection site and provoke long-term antibodies.

The experiment was designed to explore the effects and mechanism of Dilong on alleviating cyclophosphamide (CTX)-induced brain injury in mice. Fifty male SPF Kunming mice aged 6-8 weeks were randomly divided into five groups: Group A served as the control group; Group B received intraperitoneal injection of CTX; Groups C, D, and E were administered Dilong at doses of 100, 200, and 400 mg/kg respectively for 14 days after intraperitoneal injection of CTX. Results showed that after modeling, the movement speed of mice significantly decreased (P < 0.

The aim of this study was to investigate the impact of supplementary feeding with Chinese herbal mixtures on perinatal sows, focusing on their reproductive performance, immunity and breast milk quality. Sixty healthy pregnant sows (Large white, 4 parities) were randomly allocated into five treatment groups ( = 12 per group): the control group received a basal diet, the TRT1 group received a basal diet supplemented with 2 kg/t Bazhen powder (BZP), while the TRT2, TRT3, and TRT4 groups received a basal diet supplemented with 1 kg/t, 2 kg/t, and 3 kg/t Qi-Zhu-Gui-Shao soothing liver and replenishing blood powder (QZGSP), respectively. The trial lasted for a duration of 5 weeks, commencing from day 100 of gestation and concluding on day 21 postpartum.

As indispensable components of vaccines, adjuvants play a critical role in inducing potent immune responses. In our previous study, we isolated and purified a water-soluble polysaccharide from Poria cocos (PCP), and found that the PCP had the potential to act as an immunostimulant to induce a balanced Th1/Th2 immune response. However, the PCP showed effective immunomodulatory activity only at high concentrations.

Human microbiome contains various microbial macromolecules with important biological functions. The Hidden Markov Models (HMMs) can overcome the problem of low similarity sequences with distant relationships and are widely implemented within various sequence alignment softwares. However, the HMM-based sequence alignments can generate a large number of results, how to quickly screen and batch extract target homologs from microbiomes is the major sticking points.

Article Synopsis
  • - The study focuses on how the self-assembly of type I collagen (Col) can be influenced to form cyclic-bending fibrils, which are important for understanding various diseases.
  • - Researchers controlled the structure of polyimide (PI) molecular chains through a process of layering and baking, resulting in a regular hexagonal shape for the Col fibrils when they reacted on these specially prepared film surfaces.
  • - The findings highlight the ability to manipulate Col fibril morphologies and shed light on their potential biomedical implications, particularly regarding their shapes and alignment in a uniaxial direction.

Due to their safety and efficacy, aluminium salts (Alum) are considered the most important adjuvants in human vaccines. However, Alum adjuvants are unable to elicit a cellular immune response, which is vital for the prevention of various chronic infectious diseases and cancers. Herein, we isolated and purified a water-soluble polysaccharide from Chinese yam, named CYP, which was primarily composed of →4)-α-D-Glcp-(1→, →4,6)-α-D-Glcp-(1→, and α-D-Glcp-(1→.

Traditional Alum adjuvants mainly elicit a Th2 humoral immune response, but fail to generate a robust Th1 cellular immune response. However, the cellular immune response is essential for vaccination against cancer and a number of chronic infectious diseases, including human immunodeficiency virus infection and tuberculosis. In our previous study, we demonstrated that the polysaccharide from Poria cocos (PCP) has the potential to serve as an immunologic stimulant, enhancing both humoral and cellular immune responses.

In the biomedical fields of bone regenerative therapy, the immobilization of proteins on the bioceramic particles to maintain their highly ordered structures is significantly important. In this review, we comprehensively discussed the importance of the specific surface layer, which can be called "non-apatitic layer", affecting the immobilization of proteins on particles such as hydroxyapatite and amorphous silica. It was suggested that the water molecules and ions contained in the non-apatitic layer can determine and control the protein immobilization states.

Adjuvants, as the essential component of vaccines, are crucial in enhancing the magnitude, breadth and durability of immune responses. Unfortunately, commonly used Alum adjuvants predominantly provoke humoral immune response, but fail to evoke cellular immune response, which is crucial for the prevention of various chronic infectious diseases and cancers. Thus, it is necessary to develop effective adjuvants to simultaneously induce humoral and cellular immune response.
