Glomerular Basement Membrane: Lamina rara, Lamina densa

Kidney and Blood Pressure Research, 1981
Electron immunohistochemical and histochemical studies of glomerular and tubular basement membranes were undertaken to elucidate the relationship between lamina rara and lamina densa. Our results indicate that the lamina rara is not a fixation artifact and it has common antigenic determinants with lamina densa (type IV collagen antigens).

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Morphological comparison of astrocytes in the lamina cribrosa and glial lamina

Investigative Ophthalmology & Visual Science
Abstract Purpose Although the mechanisms underlying glaucomatous neurodegeneration are not yet well understood, cellular and small animal models suggest that LC astrocytes undergo early morphologic and functional changes, indicating their role as early responders to glaucomatous ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
