Small-molecule CBP/p300 histone acetyltransferase inhibition mobilizes leukocytes from the bone marrow via the endocrine stress response. Immunity 2024; 57:364-378.e9. [PMID: 38301651 PMCID: PMC10923082 DOI: 10.1016/j.immuni.2024.01.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 12/01/2023] [Accepted: 01/08/2024] [Indexed: 02/03/2024]
Abstract
Mutations of the CBP/p300 histone acetyltransferase (HAT) domain can be linked to leukemic transformation in humans, suggestive of a checkpoint of leukocyte compartment sizes. Here, we examined the impact of reversible inhibition of this domain by the small-molecule A485. We found that A485 triggered acute and transient mobilization of leukocytes from the bone marrow into the blood. Leukocyte mobilization by A485 was equally potent as, but mechanistically distinct from, granulocyte colony-stimulating factor (G-CSF), which allowed for additive neutrophil mobilization when both compounds were combined. These effects were maintained in models of leukopenia and conferred augmented host defenses. Mechanistically, activation of the hypothalamus-pituitary-adrenal gland (HPA) axis by A485 relayed shifts in leukocyte distribution through corticotropin-releasing hormone receptor 1 (CRHR1) and adrenocorticotropic hormone (ACTH), but independently of glucocorticoids. Our findings identify a strategy for rapid expansion of the blood leukocyte compartment via a neuroendocrine loop, with implications for the treatment of human pathologies.

[PMID: 37962004 PMCID: PMC10767608 DOI: 10.1002/mgg3.2318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 08/24/2023] [Accepted: 10/13/2023] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND Cornelia de Lange syndrome (CdLS) is mainly characterized by specific facial features, growth retardation, and bone deformities. Seven genes reportedly cause CdLS. Recent research has reported that loss-of-function variants affecting MAU2, which encodes a regulator of the cohesin complex, can cause CdLS. Thus far, only one MAU2-CdLS case has been reported worldwide. METHODS We detected a novel variant in MAU2 gene, NM_015329, c.526C>T (p.Arg176Trp) in a Chinese patient with CdLS, constructed a plasmid for in vitro transcriptional and protein level analysis, and analyzed the interaction between the MAU2/NIPBL complex using molecular dynamics (MD). RESULTS The results showed that the level of the exogenous MAU2 mutant protein was significantly reduced compared with that of the exogenous wild-type protein. However, MD analysis predicted an increased binding free energy between the MAU2 and NIPBL proteins that may impact the structural stability of the complex. CONCLUSION We investigated a MAU2-CdLS case in a Chinese family, which strengthens the association between MAU2 variants and CdLS phenotypes. We therefore propose that MAU2 be included in the CdLS gene screening list.

Transcriptomic responses of peripheral blood mononuclear cells to cyclosporin and etanercept in a female infant with juvenile generalized pustular psoriasis. Exp Dermatol 2023; 32:1299-1305. [PMID: 37194367 DOI: 10.1111/exd.14835] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 05/02/2023] [Accepted: 05/04/2023] [Indexed: 05/18/2023]
Abstract
Generalized pustular psoriasis (GPP) is a rare but severe form of psoriasis. An early onset of the diseases is correlated with mutations among IL36RN, CARD14, AP1S3, MPO and SERPINA3 genes. Systemic biological agents including anti-TNF-α, anti-IL-17, anti-IL-12/IL-23, anti-IL1R, anti-IL1β and anti-IL-36R act as novel treatment methods for GPP. Herein we report a female infant clinically diagnosed with GPP since she was 10-month-old. Results of whole-exome sequencing (WES) and Sanger sequencing revealed a reported heterozygous IL36RN (c.115+6T>C) and another reported heterozygous SERPINA3 frame-shifting variant (c.1247_1248del). Initial cyclosporin treatment for the patient led to a partial remission of the symptoms. However, the patient reached nearly total remission of pustules and erythema after anti-TNF-α inhibitor etanercept treatment. Results of further RNA sequencing (RNA-seq) done on peripheral blood mononuclear cells correlated with the clinical responses, showing that cyclosporin suppressed a portion of the neutrophil-related genes, while most genes associated with neutrophil activation, neutrophil-mediated immunity and degranulation were downregulated by the subsequent etanercept treatment. We report this case to demonstrate WES and RNA-seq in combination could come in handy in reaching a precise diagnosis and in evaluating or even predicting the molecular alterations underlying clinical treatment effectiveness.

Abstract
Rubinstein-Taybi Syndrome is a rare congenital multisystem syndrome inherited in an autosomal dominant pattern caused by mutations in CREBBP and EP300 genes in approximately 60% and 10% respectively. These genes encode two highly evolutionarily conserved, ubiquitously expressed, and homologous lysine-acetyltransferases, that are involved in number of basic cellular activities, such as DNA repair, cell proliferation, growth, differentiation, apoptosis of cells, and tumor suppression. It is mainly characterized by global developmental delay, moderate to severe intellectual disability, postnatal retardation, microcephaly, skeletal anomalies including broad/short, angled thumbs and/or large first toes, short stature, and dysmorphic facial features. There is an increased risk to develop tumors mainly meningiomas and pilomatrixomas, without a clear genotype-phenotype correlation. Although not considered as characteristic manifestations, numerous cutaneous anomalies have also been reported in patients with this entity. Both susceptibility to the formation of keloids and pilomatricomas are the most often associated cutaneous features. In this review, we discuss the genetics, diagnosis, and clinical features in Rubinstein-Taybi Syndrome with a review of the major dermatological manifestations.
