Abstract
A well preserved immune system is a powerful tool to prevent foreign invasion or to suppress internal mutation, which must be tightly controlled by co-stimulatory molecules in different pathophysiological conditions. One such critical molecule is OX40L expressed on activated antigen-presenting cells (APCs). Consistently, its abnormality is associated with various immunological disorders such as autoinflammatory diseases and allergy. However, a comprehensive analysis of the immune-moderating role of OX40L in dendritic cells (DCs), the most powerful APCs to initiate immune responses in vivo, and investigation of its anti-tumor efficacy in the disease setting have not been performed properly. In this study, genetic approaches for both gain-of-function and reduction-of-function were employed to reveal that OX40L was required for the efficient presentation, but not uptake, of antigens by DCs to stimulate CD4+ , as well as CD8+ T cells in vivo. As a result, CD4+ T cells were promoted towards Th1, but inhibited on Treg differentiation, by the LPS-induced OX40L on DCs, which was supported by their altered expression of co-inhibitory receptor, PD-L1. CD8+ T cells, on the other hand, also enhanced their cytotoxicity towards target cells in response to OX40L expression on the DCs transferred in vivo. Finally, in a DC-mediated tumor immunity model, the strong immunogenic roles of OX40L on DCs led to better metastasis inhibition in vivo. Collectively, our results demonstrate that OX40L could serve as a potential target in the DC-based vaccine for enhanced anti-tumor efficacy in vivo.

Abstract
Acute lung injury (ALI) is a pulmonary illness with a high burden of morbidity and mortality around the world. Chronic lung diseases also represent life-threatening situations. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a type of long non-coding RNA (lncRNA) and is highly abundant in lung tissues. MALAT1 can function as a competitive endogenous RNA (ceRNA) to impair the microRNA (miRNA) inhibition on targeted messenger RNAs (mRNAs). In this review, we summarized that MALAT1 mainly participates in pulmonary cell biology and lung inflammation. Therefore, MALAT1 can positively or negatively regulate ALI and chronic lung diseases (e.g., chronic obstructive pulmonary disease (COPD), bronchopulmonary dysplasia (BPD), pulmonary fibrosis, asthma, and pulmonary hypertension (PH)). Besides, we also found a MALAT1-miRNA-mRNA ceRNA regulatory network in acute and chronic lung diseases. Through this review, we hope to cast light on the regulatory mechanisms of MALAT1 in ALI and chronic lung disease and provide a promising approach for lung disease treatment.
