Science - Abstract
Abstract Molecular similarities between embryonic and malignant cells can be exploited to target tumors through specific signatures absent in healthy adult tissues. One such embryonic signature tumors express is oncofetal chondroitin sulfate (ofCS), which supports disease progression and dissemination in cancer. Here, we report the identification and characterization of phage display-derived antibody fragments recognizing two distinct ofCS epitopes. These antibody fragments show binding affinity to ofCS in the low nanomolar range across a broad selection of solid tumor types in vitro and in vivo with minimal binding to normal, inflamed, or benign tumor tissues. Anti-ofCS antibody drug conjugates and bispecific immune cell engagers based on these targeting moieties disrupt tumor progression in animal models of human and murine cancers. Thus, anti-ofCS antibody fragments hold promise for the development of broadly effective therapeutic and diagnostic applications targeting human malignancies.

International audience; Secretory intestinal IgA can protect from re-infection with rotavirus (RV), but very little is known about the mechanisms that induce IgA production during intestinal virus infections. Classical dendritic cells (cDCs) in the intestine can facilitate both T cell-dependent and -independent secretory IgA. Here, we show that BATF3-dependent cDC1, but not cDC2, are critical for the optimal induction of RV-specific IgA responses in the mesenteric lymph nodes. This depends on the selective expression of the TGF beta-activating integrin alpha v beta 8 by cDC1. In contrast, alpha v beta 8 on cDC1 is dispensible for steady state immune homeostasis. Given that cDC2 are crucial in driving IgA during steady state but are dispensable for RV-specific IgA responses, we propose that the capacity of DC subsets to induce intestinal IgA responses reflects the context, as opposed to an intrinsic property of individual DC subsets.

Background: MicroRNAs (miRNAs) are short non-coding RNA molecules which regulate gene expression post-transcriptionally and are involved in a multitude of cellular processes. MiRNAs are known to be very stable compared to messenger RNAs (mRNAs), making them excellent candidates as biomarkers for disease. Recently, studies have suggested that miRNA stability in formalin fixed samples might depend on their nucleotide composition. Objective: To explore the stability of a panel of miRNAs isolated from porcine blood and lung tissue after heat and enzyme treatment. Method: Porcine RNA isolated from lung tissue and blood leukocytes was used for this study. RNA samples were exposed to heat treatment and RNAse A digestion. The levels of selected miRNAs were measured by means of qPCR before and after heat and enzyme treatment. Results: Fourteen miRNAs were successfully analysed, and they were found to degrade differently after exposure to heat or RNAse A. MiRNAs with Conclusion: This is the first study showing that different miRNAs isolated from lung tissue display unequal stability after heat treatment, probably based on their nucleotide composition, highlighting the importance of considering the miRNA sequence when investigating their value as biomarkers.

- Abstract
Initiation of adaptive immunity to particulate antigens in lymph nodes largely depends on their presentation by migratory dendritic cells (DCs). DC subsets differ in their capacity to induce specific types of immunity, allowing subset-specific DC-targeting to influence vaccination and therapy outcomes. Faithful drug design, however, requires exact understanding of subset-specific versus global activation mechanisms. cDC1, the subset of DCs that excel in supporting immunity toward viruses, intracellular bacteria, and tumors, express uniquely high levels of the pattern recognition receptor TLR3. Using various murine genetic models, we show here that both, the cDC1 and cDC2 subsets of cDCs are activated and migrate equally well in response to TLR3 stimulation in a cell extrinsic and TNF-α dependent manner, but that cDC1 show a unique requirement for type I interferon signaling. Our findings reveal common and differing pathways regulating DC subset migration, offering important insights for the design of DC-based vaccination and therapy approaches.
