Abstract
Intrapleural immunotherapies have emerged as a prominent field in treating malignant pleural effusion (MPE). Among these, bacteria-based intrapleural therapy has exerted an anti-MPE effect by immuno-stimulating or cytotoxic properties. We previously engineered a probiotic Lactococcus lactis (FOLactis) expressing a fusion protein of Fms-like tyrosine kinase 3 and co-stimulator OX40 ligands. FOLactis activates tumor antigen-specific immune responses and displays systemic antitumor efficacy via intratumoral delivery. However, no available lesions exist in the pleural cavity of patients with MPE for intratumoral administration. Therefore, we further optimize FOLactis to treat MPE through intrapleural injection. Intrapleural administration of FOLactis (I-Pl FOLactis) not only distinctly suppresses MPE and pleural tumor nodules, but also significantly extends noticeable survival in MPE-bearing murine models. The proportion of CD103+ dendritic cells (DCs) in tumor-draining lymph nodes increases three-fold in FOLactis group, compared to the wild-type bacteria group. The enhanced DCs recruitment promotes the infiltration of effector memory T and CD8+ T cells, as well as the activation of NK cells and the polarization of macrophages to M1. Programmed death 1 blockade antibody combination further enhances the antitumor efficacy of I-Pl FOLactis. In summary, we first develop an innovative intrapleural strategy based on FOLactis, exhibiting remarkable efficacy and favorable biosafety profiles. These findings suggest prospective clinical translation of engineered probiotics for managing MPE through direct administration into the pleural cavity.

Abstract
BACKGROUND Many studies have investigated the efficacy and safety of lentinan combined with cisplatin versus cisplatin alone for controlling malignant pleural effusion (MPE). This study is a meta-analysis of available evidence. MATERIALS AND METHODS Seventeen studies reporting lentinan combined with cisplatin versus cisplatin alone for controlling MPE were reviewed. Pooled odds ratios and hazard ratio with 95% confidence intervals were calculated using the fixed effects model of meta-analysis. RESULTS The overall response rate (ORR) of lentinan combined with cisplatin for controlling MPE was significantly higher than that of cisplatin alone (P < 0.001). In addition, lentinan combined with cisplatin showed a better benefit of quality of life (QOL) compared with cisplatin alone (P < 0.001). The main adverse effects (AEs) found in the control plan were hematological reactions, nausea/vomiting, chest pain and fever. However, the presence of lentinan did not have an extra influence on the incidence of AEs (P > 0.05). CONCLUSIONS Intrapleural injection of lentinan combined with cisplatin had a better benefit of ORR and QOL for controlling MPE, compared with cisplatin alone. Moreover, lentinan combined with cisplatin had a similar incidence of AEs with cisplatin alone.

Abstract
BACKGROUND Intrapleural injection of CTB-Alexa 488, a retrograde tracer, provides an alternative labeling technique to the surgically invasive laparotomy required for intradiaphragmatic injection. However, CTB-Alexa 488 is incapable of crossing synapses restricting the tracer to the phrenic nuclei and the intercostal motor nuclei in the spinal cord. NEW METHOD Intrapleural injection of WGA-Alexa 488, a transsynaptic tracer, provides a method to label the respiratory motor pathway in both the spinal cord and medulla. Intradiaphragmatic injection of WGA-Alexa 594 and vagal nerve injections of True blue were used to confirm the phrenic nuclei and to differentiate between the rVRG and the NA in the medulla. RESULTS Following intrapleural injection, WGA-Alexa 488 was retrogradely transported to the phrenic nuclei and to the intercostal motor nuclei. Subsequently WGA-Alexa 488 was transsynaptically transported from the phrenic motoneurons to the pre-motor neurons in the rVRG that provide the descending drive to the phrenic neurons during inspiration. In addition WGA-Alexa 488 was identified in select cells of the NA confirmed by a dual label of both WGA-Alexa 488 and True blue. COMPARISON WITH EXISTING METHOD WGA-Alexa 488 demonstrates retrograde transsynaptic labeling following intrapleural injection whereas the previous method of injecting CTB-Alexa 488 only demonstrates retrograde labeling. CONCLUSIONS Intrapleural injection of WGA-Alexa fluor conjugates is an effective method to transsynaptically label the phrenic motor system providing an alternative for the invasive laparotomy required for intradiaphragmatic injections. Furthermore, the study provides the first anatomical evidence of a direct synaptic relationship between rVRG and select NA cells.
