Mechanism of Ciliary Motion01:05

Mechanism of Ciliary Motion

6.0K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Microbiome of the Eye

62
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...

Summary
This summary is machine-generated.

An unusual intraocular foreign body (IOFB) was found to be an eyelash in a patient with no history of trauma. Pathologic analysis confirmed the IOFB as a cilium, presenting a rare clinical scenario.

Area of Science:

  • Ophthalmology
  • Ophthalmic Pathology

Background:

  • Intraocular foreign bodies (IOFBs) are uncommon, with eyelashes being a rare type.
  • Eyelash IOFBs are typically associated with penetrating eye trauma.

Purpose of the Study:

  • To report a rare case of an intraocular cilium presenting without a history of trauma.
  • To describe the clinical and pathological findings of an unusual eyelash IOFB.

Main Methods:

  • A 58-year-old female presented with symptoms of floaters, decreased vision, and redness.
  • Ophthalmic examination revealed a white, worm-like object in the anterior vitreous.
  • Pars plana vitrectomy was performed for IOFB removal, followed by pathological analysis.

Main Results:

  • Pathological examination identified the IOFB as a cilium (eyelash) encased in collagen fibers and adipose tissue.
  • Vitreous cultures were negative for pathogens.
  • The patient's presentation was unique due to the "fluffy" white appearance resembling a parasite.

Conclusions:

  • Intraocular cilia without a history of trauma are exceptionally rare.
  • The presence of adipose tissue suggests potential drag during penetration.
  • This case highlights the importance of thorough examination and pathological analysis for diagnosing unusual IOFBs.
