The retina shares prominent similarities with the brain and thus represents a unique window to study vasculature and neuronal structure in the brain non-invasively. This protocol describes a method to study dementia using retinal imaging techniques. This method can potentially aid in diagnosis and risk assessment of dementia.

This video demonstrates three types of morphometric analyses of the retina, which include measuring the inner nuclear layer thickness, quantifying the number of retinal ganglion cells (RGCs) and measuring the sizes of RGCs. The technique can offer a simple but scientific platform for morphometric analyses.

What is the Immune System?

Overview The immune system comprises diverse biological structures and processes that protect the body from disease. These processes can be classified into innate and adaptive immunity. To work effectively, the immune system needs to detect pathogens by distinguishing the body’s own structures from foreign elements. If this determination fails, autoimmune diseases occur in which the immune system reacts against the body’s own tissue. The Innate Immune System Acts Fast and Non-specifically

GTPases and their Regulation

2020
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒ small G-proteins consisting of a single domain and large multi-domain G-proteins. Large G-proteins, also known...
FAQs
The blood-retina barrier limits the entry of circulating immune components into retinal tissue, helping restrict unnecessary inflammatory activity. This protection does not eliminate immune surveillance. Resident microglia and retinal cells remain positioned to detect stress and adjust local responses, allowing the retina to balance restricted exposure with the need to respond to injury.
Resident microglia and retinal cells detect stress within the tissue and modify local immune responses. Their activity can support homeostasis or initiate repair, depending on the retinal condition. This responsive role is important because the same regulatory system must preserve neural tissue under normal conditions while still recognizing disturbances that require an immune reaction.
Cytokine and complement responses are among the local mechanisms that retinal cells can adjust when maintaining homeostasis or responding to stress. Their regulation helps determine whether inflammation remains controlled or becomes damaging. Understanding these responses is therefore relevant to designing treatments that reduce harmful inflammation without removing protective immune functions.
Failure of retinal immune controls can produce persistent inflammation rather than a temporary response associated with repair or homeostasis. Continued inflammatory activity may damage photoreceptors, retinal neurons, and blood vessels. These consequences explain why immune regulation is clinically important: disruption can affect both the neural structures responsible for vision and the retinal vasculature.
In medicine, retinal immune regulation provides a framework for studying uveitis, diabetic retinopathy, age-related macular degeneration, and other retinal disorders. The connection is clinically significant because abnormal inflammatory control may contribute to tissue injury across different diseases. Research can therefore examine shared regulatory processes while considering how each disorder affects retinal cells and vessels.
A central therapeutic goal is to suppress harmful inflammation while preserving protective immunity. Broadly eliminating immune activity could interfere with surveillance, homeostasis, or repair, whereas insufficient control may allow persistent inflammation to damage retinal tissue. This balance guides treatment development for disorders in which inflammatory injury threatens photoreceptors, neurons, blood vessels, or vision.
Retinal immune regulation connects immune mechanisms to vision preservation because inflammatory damage can affect photoreceptors and retinal neurons, while vascular injury can further compromise retinal function. Studying surveillance, tolerance, inflammation, and repair together helps researchers interpret how immune changes influence neural tissue. This integrated perspective supports investigation of retinal disease and therapeutic strategies.
