TCR transgenic clone selection guided by immune receptor analysis and single-cell RNA expression of polyclonal responders.
Elife

Laboratory of Immunoregulation and Mucosal Immunology, VIB Center for Inflammation Research, Ghent, Belgium.
Since the precursor frequency of naive T cells is extremely low, investigating the early steps of antigen-specific T cell activation is challenging. To overcome this detection problem, adoptive transfer of a cohort of T cells purified from T cell receptor (TCR) transgenic donors has been extensively used but is not readily available for emerging pathogens. Constructing TCR transgenic mice from T cell hybridomas is a labor-intensive and sometimes erratic process, since the best clones are selected based on antigen-induced CD69 upregulation or IL-2 production in vitro, and TCR chains are polymerase chain reaction (PCR)-cloned into expression vectors.

Women with extremely dense breasts are at a higher risk of breast cancer, and the sensitivity of mammography in this group is reduced due to the masking effect of overlapping tissue. This review examines supplemental screening methods to improve detection in this population, with a focus on MRI. Morphologic techniques offer limited benefits, digital breast tomosynthesis (DBT) shows inconsistent results, and ultrasound (US), while improving cancer detection rates (CDR), results in a higher rate of false positives.

Ann Neurol
January 2025
School of Biotechnology and Biomolecular Sciences, University of New South Wales, Sydney, New South Wales, Australia.
Unlabelled: Congenital titinopathy has recently emerged as one of the most common congenital muscle disorders.
Objective: To better understand the presentation and clinical needs of the under-characterized extreme end of the congenital titinopathy severity spectrum.
Methods: We comprehensively analyzed the clinical, imaging, pathology, autopsy, and genetic findings in 15 severely affected individuals from 11 families.
Orbital mesenchymal chondrosarcoma: a case report.
J Int Med Res

Department of Orbital Disease and Ocular Plastic Surgery, The Second Hospital of Jilin University, No. 4026 Yatai Street, Changchun, Jilin Province, China.
Extraskeletal orbital mesenchymal chondrosarcoma is an extremely rare and highly aggressive tumor. We herein report a case involving a woman in her early 20s diagnosed with orbital mesenchymal chondrosarcoma. This case report aims to increase recognition and understanding of this condition.

Complex Operational Unit of Sports Traumatology and Joint Reconstruction, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Largo Agostino Gemelli 8, 00168 Roma, Italy.
Multi-ligament reconstruction in adolescent patients affected by congenital femoral deficiency is an extremely rare and delicate surgical procedure. There are very few reported cases of complete anterior and posterior cruciate ligament agenesis in these patients. We present a complex case of a 16-year-old girl affected by congenital femoral deficiency and ipsilateral tibial hypoplasia who was treated successfully for a complete agenesis of the anterior (ACL) and posterior (PCL) cruciate ligament with single-sitting ACL and PCL reconstruction.
