In Vitro Development of a Muscle-Tendon Junction Construct Using Decellularised Extracellular Matrix: Effect of Cyclic Tensile Loading

[Biomaterials Advances] Decellularized extracellular matrix-derived from sheep muscle tendon junction (MTJ) was used to provide a scaffold for the MTJ with the relevant mechanical properties and differentiation cues such as the relase of growth factors.

NIH Awards Hesperos Research Grant to Develop Animal-Free Botox Testing Platform

[Hesperos, Inc.] Hesperos was awarded a $2 million research grant by the National Center for Advancing Translational Sciences in collaboration with the US FDA. The goal of the effort is to develop an advanced testing platform capable of assessing the potency of the Botulinum Toxin without the need for animal testing.

Establishment of Human Hematopoietic Organoids for Evaluation of Hematopoietic Injury and Regeneration Effect

[Stem Cell Research & Therapy] To manufacture hematopoietic organoids, researchers obtained CD34+ hematopoietic stem and progenitor cells from human embryonic stem cells using stepwise induction and immunomagnetic bead-sorting.

Heterozygous RB1 Mutation Enhanced ATP Production in Human iPSC-Derived Retinal Organoids

[Molecular Biology Reports] Scientists gained further insight into the molecular disruptions in the RB1+/− retinal organoids, they performed a high throughput RNA sequencing analysis.

Synergistic Hyperactivation of Both mTORC1 and mTORC2 Underlies the Neural Abnormalities of PTEN-Deficient Human Neurons and Cortical Organoids

[Cell Reports] Investigators showed that pluripotent stem cell-derived phosphatase and tensin homolog (PTEN) mutant human neurons, neural precursors, and cortical organoids recapitulated disease-relevant phenotypes, including hypertrophy, electrical hyperactivity, enhanced proliferation, and structural overgrowth.

First Model of the Brain’s Information Highways Developed

[Informationsdienst Wissenschaft] Placenta organoids created from cultured human placenta cells have been used to shed light on several types of infection in early pregnancy

THEMIS Promotes T Cell Development and Maintenance by Rising the Signaling Threshold of the Inhibitory Receptor BTLA

[Proceedings Of The National Academy Of Sciences Of The United States Of America] Investigators showed that the T cell lineage protein THEMIS operates as a rheostat which restrain the signaling capacity the inhibitory receptor B- and T-lymphocyte attenuator (BTLA).

Triune Nanomodulator Enables Exhausted Cytotoxic T Lymphocyte Rejuvenation for Cancer Epigenetic Immunotherapy

[ACS Nano] Scientists presented a well-designed triune nanomodulator, termed ROCA, which demonstrated robust capabilities in tumor epigenetic modulation and immune microenvironment reprogramming for cancer epigenetic immunotherapy.

The NIH Announces Winners of the Complement-ARIE Challenge Competition

[National Institutes of Health] The Complement Animal Research In Experimentation Challenge Prize competition offered $1,000,000 in total prize money to diverse teams with ideas for new ways of using New Approach Methodologies to conduct basic research, uncover disease mechanisms, and translate knowledge into products and practice.

Atypical Chemokine Receptors in the Immune System

[Nature Reviews Immunology] The authors described the contribution of the various atypical chemokine receptors to innate and adaptive immune responses, focussing specifically on recent progress.

The Immunoglobulin Superfamily Ligand B7H6 Subjects T Cell Responses to NK Cell Surveillance

[Science Immunology] By screening for mediators of natural killer (NK) cell recognition on T cells, researchers identified the immunoglobulin superfamily ligand B7H6 to be highly expressed by activated T cells, including patient-infused CD19-targeting chimeric antigen receptor (CAR) T cells.

Antigenicity Assessment of SARS-CoV-2 Saltation Variant BA.2.87.1

[Emerging Microbes & Infections] Investigators elucidated the antigenic characteristics and immune evasion capability of BA.2.87.1. Our findings revealed that BA.2.87.1 was more susceptible to XBB-induced humoral immunity compared to JN.1.
