Significance: Laparoscopic surgery presents challenges in localizing oncological margins due to poor contrast between healthy and malignant tissues. Optical properties can uniquely identify various tissue types and disease states with high sensitivity and specificity, making it a promising tool for surgical guidance. Although spatial frequency domain imaging (SFDI) effectively measures quantitative optical properties, its deployment in laparoscopy is challenging due to the constrained imaging environment.

Unlabelled: Dendritic cells (DCs) are key regulators of adaptive immunity, guiding T helper (Th) cell differentiation through antigen presentation, co-stimulation, and cytokine production. However, in steady-state conditions, certain DC subsets, such as Langerhans cells (LCs), induce T follicular helper (Tfh) cells and B cell responses without inflammatory stimuli. Using multiple mouse models and systems, we investigated the mechanisms underlying steady-state LC-induced adaptive immune responses.

Peptide vaccines based on tumor antigens face the challenges of rapid clearance of peptides, low immunogenicity, and immune suppressive tumor microenvironment. However, the traditional solution mainly uses exogenous substances as adjuvants or carriers to enhance innate immune responses, but excessive inflammation can damage adaptive immunity. In the current study, we propose a straightforward novel nanovaccine strategy by employing homologous human ferritin light chain for minimized innate immunity and dendritic cell (DC) targeting, the cationic KALA peptide for enhanced cellular uptake, and suppressor of cytokine signaling 1 (SOCS1) siRNA for modulating DC activity.

Unlabelled: or "first, do no harm" is perhaps the most well-known aphorism in the culture of medical education. While its application to patients is well known, the injunction can also be read with medical trainees in mind. Teaching physicians have an obligation to recognize their role as moral teachers and coaches, who must consider "first, do no harm" not only when considering their patients but also when weighing the moral formation of their trainees, especially in a season in which medical educators are attempting to clarify the "harms" of medical training.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder characterized by widespread immune dysregulation that affects multiple organ systems, including the skin and cardiovascular system. The crosstalk between different cell death pathways-such as apoptosis, necroptosis, and neutrophil extracellular trap (NETosis), plays a pivotal role in the pathogenesis of SLE, influencing both cutaneous and cardiac manifestations. Cutaneous lupus erythematosus (CLE) is one of the most common early signs of SLE, affecting up to 80% of patients.

Dendritic cells (DCs) are key cellular components of the immune system and perform critical functions in innate and acquired immunity. In mammals, it is generally believed that DCs originate exclusively from hematopoietic stem cells (HSCs). Using a temporal-spatial resolved fate-mapping system, here we show that in zebrafish, DCs arise from two sources: dorsal aorta-born endothelium-derived hematopoietic progenitors (EHPs) and HSCs.
