The immunoreceptor SLAMF8 promotes the differentiation of follicular dendritic cell-dependent monocytic cells with B cell-activating ability.

Follicular dendritic cells (FDCs) play a crucial role in generating high-affinity antibody-producing B cells during the germinal center (GC) reaction. Herein, we analysed the altered gene expression profile of a mouse FDC line, FL-Y, following lymphotoxin β receptor stimulation, and observed increased Slam-family member 8 (Slamf8) mRNA expression. Forced Slamf8 expression and SLAMF8-Fc addition enhanced the ability of FL-Y cells to induce FDC-induced monocytic cell (FDMC) differentiation.

Bariatric surgery-what the ophthalmologist needs to know.

The incidence of bariatric surgery is increasing due to obesity being one of our top public health challenges. As such, bariatric-related ophthalmic changes are a potentially new clinical area of knowledge, with increasing published evidence on post-bariatric complications experienced by patients and identified by clinicians. We reviewed the available literature and summarised the different complications and potential recommendations.

Erythroderma (exfoliative dermatitis). Part 1: underlying causes, clinical presentation and pathogenesis.

Erythroderma (exfoliative dermatitis), first described by Von Hebra in 1868, manifests as a cutaneous inflammatory state, with associated skin barrier and metabolic dysfunctions. The annual incidence of erythroderma is estimated to be 1-2 per 100 000 population in Europe with a male preponderance. Erythroderma may present at birth, or may develop acutely or insidiously (due to progression of an underlying primary pathology, including malignancy).
