Context: Congenital hypothyroidism (CH) is the most common endocrine disorder in neonates, but its etiology is still poorly understood.

Objective: We performed whole exome sequencing to identify a novel causative gene for CH and functional studies to validate its role in the occurrence of CH.

Methods: Whole exome sequencing in 98 CH patients not harboring known CH candidate genes and bioinformatic analysis were performed.

The mechanisms of bifurcation, a key step in thyroid development, are largely unknown. Here we find three zebrafish lines from a forward genetic screening with similar thyroid dysgenesis phenotypes and identify a stop-gain mutation in hgfa and two missense mutations in met by positional cloning from these zebrafish lines. The elongation of the thyroid primordium along the pharyngeal midline was dramatically disrupted in these zebrafish lines carrying a mutation in hgfa or met.

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor () gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype-phenotype relationships for most variants associated with CH remain unexplored. We aimed to identify variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between genotypes and clinical phenotypes.

Congenital hypothyroidism (CH) is the most common neonatal metabolic disorder. In patients with CH in China, thyroid dyshormonogenesis is more common than thyroid dysgenesis; however, the genetic causes of CH due to thyroid dyshormonogenesis remain largely unknown. Therefore, we aimed at identifying novel candidate causative genes for CH.

Article Synopsis
  • The study investigates the causes of thyroid dysgenesis (TD) by analyzing specific thyroid cells in mice and their behavior in zebrafish embryos.
  • Researchers identified a group of thyrocytes activated by NF-κB that maintain a unique phenotype and are essential for forming new thyroid follicles.
  • The results indicate that myeloid cells and their secretion of TNF-α are crucial for the movement of thyrocytes, which is important for proper thyroid development.

Background: In several countries, thyroid dyshormonogenesis is more common than thyroid dysgenesis in patients with congenital hypothyroidism (CH). However, known pathogenic genes are limited to those directly involved in hormone biosynthesis. The aetiology and pathogenesis of thyroid dyshormonogenesis remain unknown in many patients.

Background: ISL LIM homeobox 2, also known as insulin gene enhancer protein ISL-2 (), is a transcription factor gene that participates in a wide range of developmental events. However, the role of in the hypothalamus-pituitary-thyroid axis is largely unknown.

The thyroid follicular cells originate from the foregut endoderm and elucidating which genes and signaling pathways regulate their development is crucial for understanding developmental disorders as well as diseases in adulthood. We exploited unique advantages of the zebrafish model to carry an ENU-based forward mutagenesis screen aiming at identifying genes involved in the development and function of the thyroid follicular cells. ENU is an excellent chemical mutagen due to its high mutation efficiency and an indiscriminate selection of genes.

  • Recent research indicates that CD8+ T cells are crucial in controlling HIV-1 reservoirs in individuals on antiretroviral therapy, although their exact mechanisms are still unclear.
  • In a study of 60 virologically suppressed HIV-1 patients, certain CD8+ T cell subsets were found to correlate with levels of HIV-1 DNA and RNA, revealing that specific central and terminally differentiated memory cells behaved differently in their responses.
  • The findings suggest that CCL5-secreting CD8+ T cells may play a key role in limiting HIV-1 reservoirs, paving the way for new CD8+ T cell-based treatments aimed at curing HIV-1 infection.

Characterization of T cell receptor (TCR) repertoires is essential for understanding the mechanisms of infection involving T cell adaptive immunity. The characteristics of TCR sequences and distinctive signatures of T cell subsets in tuberculous patients are still unclear. By combining single-cell TCR sequencing (sc-TCR seq) with single-cell RNA sequencing (sc-RNA seq) and flow cytometry to characterize T cells in tuberculous pleural effusions (TPEs), we identified 41,718 CD3 T cells in TPEs and paired blood samples, including 30,515 CD4 T cells and 11,203 CD8 T cells.

The complex interactions among different immune cells have important functions in the development of malignant pleural effusion (MPE). Here we perform single-cell RNA sequencing on 62,382 cells from MPE patients induced by non-small cell lung cancer to describe the composition, lineage, and functional states of infiltrating immune cells in MPE. Immune cells in MPE display a number of transcriptional signatures enriched for regulatory T cells, B cells, macrophages, and dendritic cells compared to corresponding counterparts in blood.

Objective: Congenital hypothyroidism (CH) is known to be due to thyroid dyshormonogenesis (DH), which is mostly inherited in an autosomal recessive inheritance pattern or thyroid dysgenesis (TD), whose inheritance pattern is controversial and whose molecular etiology remains poorly understood.

Design And Methods: The variants in 37 candidate genes of CH, including 25 genes related to TD, were screened by targeted exon sequencing in 205 Chinese patients whose CH cannot be explained by biallelic variants in genes related to DH. The inheritance pattern of the genes was analyzed in family trios or quartets.

Congenital hypothyroidism (CH) is a highly prevalent but treatable neonatal endocrine disorder. Thyroid dyshormonogenesis is the main cause of congenital hypothyroidism in Chinese CH patients, and DUOX2 is the most frequent mutated gene involved in H2O2 production. In humans, the primary sources for H2O2 production are DUOX1 and DUOX2, while in zebrafish there is only a single orthologue for DUOX1 and DUOX2.

The transcription factor GLIS3 is an important factor in hormone biosynthesis and thyroid development, and mutations in GLIS3 are relatively rare. Deletions of more than one of the 11 exons of GLIS3 occur in most patients with various extrathyroidal abnormalities and congenital hypothyroidism (CH), and only 18 missense variants of GLIS3 related to thyroid disease have been reported. The aim of this study was to report the family history and molecular basis of patients with CH who carry GLIS3 variants.
