Primary cilia play a pivotal role in cellular signaling and development and disruptions in ciliary form and/or function leads to human ciliopathies. Here, we examine the role of , a key component of the intraflagellar transport-A complex, in mouse forebrain development using a null allele. Our findings reveal significant microcephaly in homozygous mutants is caused by disrupted neural progenitor proliferation and differentiation.

These events are associated with innate training and can have long-term impacts on hematopoietic stem and progenitor cell (HSPC) development but can also compromise their function. While many cytokines support emergency myelopoiesis, less is known about the mechanisms that temper these events.

Despite the importance of the Hippo pathway, the in vivo functions of TEAD in mammals have not been well established. By comparing mouse mutants lacking TEAD1 and TEAD2 (TEAD1/2) to those lacking YAP/TAZ, we found that TEAD1/2 have both YAP/TAZ-dependent and -independent functions during ventral telencephalon development.

Aging often triggers dental pulp fibrosis, resulting in clinical repercussions such as increased susceptibility to dental infections, compromised tooth vitality, and reduced responsiveness to dental interventions. Despite its prevalence, the precise molecular mechanisms underlying this condition remains unclear. Leveraging single-cell transcriptome analysis from both our own and publicly available datasets, we identified Ccrl2 macrophages as particularly vulnerable during the early stages of aging.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immature myeloid cells playing a critical role in immune suppression. In vitro-generated MDSCs are a convenient tool to study the properties of tumour-associated MDSCs. Here, we compared six protocols for in vitro generation of functional mouse MDSCs from bone marrow progenitors.
