Questions concerning the influences of nuclear receptors and their ligands on mammalian B cells are vast in number. Here, we briefly review the effects of nuclear receptor ligands, including estrogen and vitamins, on immunoglobulin production and protection from infectious diseases. We describe nuclear receptor interactions with the B cell genome and the potential mechanisms of gene regulation. Attention to the nuclear receptor/ligand regulation of B cell function may help optimize B cell responses, improve pathogen clearance, and prevent damaging responses toward inert- and self-antigens.

We reported the pseudoprogression in an elderly patient with advanced gastric cancer after chimeric antigen receptor (CAR)-T cell therapy. The hepatic metastases enlarged 1 month after CAR-T cell infusion and then shrunk the next month as seen through computed tomography scanning. Based on a comprehensive evaluation that includes imaging, pathology, serum tumor markers, and clinical symptoms, we arrived at a diagnosis of pseudoprogression after CAR-T cell therapy, which has not been reported in previous studies.

Objectives: Retinoid X receptors (RXRs) are nuclear hormone receptors (NRs) functioning as transcription factors. There are three RXR isoforms: RXRA (NR2B1), RXRB (NR2B2), and RXRG (NR2B3). RXRs serve as master regulators of gene networks governing cell growth, differentiation, survival, and death.

Background: The vitamin D pathway contributes to the microbicidal activity of macrophages against infection. In addition to induction of this pathway, interferon-gamma (IFNγ), interleukin (IL)-15, and IL32γ are part of a network of pro-inflammatory cytokines. The aim of this study was to evaluate single-nucleotide polymorphisms (SNPs) in the components of the vitamin D pathway and associated cytokine genes that could be related to resistance or susceptibility to American tegumentary leishmaniasis (ATL).

In recent years, chimeric antigen receptor T-cell (CAR-T) therapy has made groundbreaking progress in the treatment of various cancer types, particularly hematological malignancies. In the meantime, various preclinical and clinical studies have extensively explored dual-target CAR-T therapies which can be designed to recognize two antigens simultaneously based on the immunophenotype of tumor cells. Compared with single-target CAR-T approach, dual-target CAR-T therapies demonstrate varying degrees of superior antitumor CAR effects, prevent antigen escape and relapse, reduce on-target off-tumor effects, and ensure durable responses in different types of cancer.

Cutaneous melanoma is one of the most aggressive skin cancers originating from skin pigment cells. Patients with advanced melanoma suffer a poor prognosis and generally cannot benefit well from surgical resection and chemo/target therapy due to metastasis and drug resistance. Thus, adoptive cell therapy (ACT), employing immune cells with specific tumor-recognizing receptors, has emerged as a promising therapeutic approach to display on-tumor toxicity.
