Female CBi mice subjected to multiple exposures to halothane inhalation anesthesia before mating were investigated for the potential effects of such intervention on a specific antibody response mounted by them and their offspring. An assessment of the toxicologic and reproductive performance of female mice undergoing anesthesia was also performed. Adult female mice received three episodes of halothane anesthesia at weekly intervals. Seventy-two hours after the last dose, mice were subjected to the following procedures: 1) study of the specific humoral immune response to sheep red blood cells (SRBC); 2) hematologic, hepatologic, and histopathologic studies; and 3) mating with syngeneic sires. Halothane-treated females had increased amounts of specific antibody secreting B cells, with liver studies showing evidence of microscopic fatty changes and decreased lipid peroxidation. Anesthesia did not alter reproductive performance but lowered offspring survival. Offspring displayed depressed antibody response after challenge with SRBC at weaning and at 60 d of age. The anti-SRBC antibody response that was found to be enhanced in halothane anesthetized females, seemed to be conversely impaired when studied in the offspring.

Introduction: Atopic dermatitis (AD) is a common and relapsing skin disease characterized by skin barrier dysfunction, inflammation, and chronic pruritus. Both cutaneous barrier dysfunction and immune dysregulation are critical etiologies of the pathology of AD. Although various anti-inflammatory pharmacological agents, including cytokine inhibitors and signaling pathway blockers, have been developed recently, keeping the skin clean is of utmost importance in maintaining physiological cutaneous barrier function and avoiding an AD flare.

Background: Maternal nutrition profoundly influences offspring health, impacting both prenatal and early postnatal development. Previous studies have demonstrated that maternal dietary habits can affect key developmental pathways in the offsprings, including those related to lung function and disease susceptibility. However, the sex-specific impact of a maternal high-salt diet (HSD) on offspring lung injury remains poorly understood.

The decline of oocyte quality with advanced maternal age has a detrimental effect on female fertility. However, there is limited knowledge of therapeutic options and their mechanisms to improve oocyte quality in reproductively older women. In this study, we demonstrated that supplementation of salidroside improves the oocyte quality of reproductively old mice.

Dry eye disease (DED) is an inflammatory disorder in which CD4 T cells play a significant role in its pathogenesis. A CD4 T cell subset termed granulocyte-macrophage colony-stimulating factor-producing T helper (ThGM) cells would contribute to DED pathogenesis. However, the mechanisms by which the activity of ThGM cells is modulated are not thoroughly understood.

Background: Patients with estrogen receptor (ER)-positive breast cancer (BC) can be treated with endocrine therapy targeting ER, however, metastatic recurrence occurs in 25% of the patients who have initially been treated. Secreted proteins from tumors play important roles in cancer metastasis but previous methods for isolating secretory proteins had limitations in identifying novel targets.
Methods: We applied an in situ secretory protein labeling technique using TurboID to analyze secretome from tamoxifen-resistant (TAMR) BC.
