Folds in the cerebral cortex in mammals are believed to be key structures for accommodating increased cortical neurons in the cranial cavity. However, the mechanisms underlying cortical folding remain largely unknown, mainly because genetic manipulations for the gyrencephalic brain have been unavailable.

The innate immune system protects cells against viral pathogens in part through the autocrine and paracrine actions of interferons (IFN)-α/β (type I), -γ (type II), and -λ (type III).

Abstract

The constant regeneration of stomach epithelium is driven by long-lived stem cells, but the mechanism that regulates their turnover is not well understood. We have recently found that the gastric pathogen Helicobacter pylori can activate gastric stem cells and increase epithelial turnover, while Wnt signalling is known to be important for stem cell identity and epithelial regeneration in several tissues.

Abstract

Background and Aims

In 2014 we observed a noticeable increase in sudden deaths of green tree pythons (Morelia viridis). Pathological examination revealed accumulation of mucoid material within airways and lung, associated with enlargement of the entire lung.

Mammalian members of the forkhead box protein O (FoxO) class of transcription factors are implicated in the regulation of oxidative stress, and FoxO proteins are negatively regulated by the phosphatidylinositol 3-kinase (PI3K)-AKT signaling pathway. We examined the effect of Klotho on the PI3K/AKT pathway and manganese superoxide dismutase (MnSOD) during tacrolimus (Tac)-induced oxidative stress.

Limited longitudinal data exist on the effect of HIV on adipose tissue (AT). We found an increase in CD4+ cells and detectable SHIV-RNA in AT during acute SHIV infection. SHIV-RNA+ cells were rare, suggesting that AT is unlikely to be a major source of productively infected cells in SHIV infection.

The epithelial lining of the Fallopian tube is vital for fertility, providing nutrition to gametes, and facilitating their transport. It is composed of two major cell types: secretory cells and ciliated cells. Interestingly, human ovarian cancer precursor lesions are primarily consisting of secretory cells. It is unclear why secretory cells are the dominant cell type in these lesions.

Endoplasmic reticulum (ER) stress is commonly observed in intestinal epithelial cells (IECs) and can, if excessive, cause spontaneous intestinal inflammation as shown by mice with IEC-specific deletion of X-box-binding protein 1 (Xbp1), an unfolded protein response-related
