Follicular dendritic cells: dynamic antigen libraries

Nature Reviews Immunology, 2014
Follicular dendritic cells (FDCs) are essential for high-affinity antibody production and for the development of B cell memory. Historically, FDCs have been characterized as 'accessory' cells that passively support germinal centre (GC) responses. However, recent observations suggest that FDCs actively shape humoral immunity.

Follicular lymphoma dynamics

2021
Follicular lymphoma (FL) is an indolent yet challenging disease. Despite a generally favorable response to immunochemotherapy regimens, a fraction of patients does not respond or relapses early with unfavorable prognosis. For the vast majority of those who initially respond, relapses will repeatedly occur with increasing refractoriness to available ...

Follicular dynamics in Mangalarga mares

Equine Veterinary Journal, 1997
Summary Ovarian follicular activity was studied by ultrasonography during 17 oestrous cycles in 9 Mangalarga mares during the second half of the ovulatory season. Sixteen oestrous cycles were considered normal and one 3‐wave cycle showing a prolonged luteal phase was considered atypical.

Follicular dynamics around the recruitment of the first follicular wave in the cow.

Biology of reproduction, 2003
The present study aimed to test the generally accepted view that a follicular wave starts with follicles newly recruited from the population smaller than 3 mm, which later compete for dominance. According to this view, subordinate follicles are expected to be too atretic to join the next follicular wave.

Follicular and hormonal dynamics during the first follicular wave in heifers

Theriogenology, 1999
A few days after the first follicular wave emerges as 4-mm follicles, follicular deviation occurs wherein 1 follicle of the wave continues to grow (dominant follicle) while the others regress. The objectives of this study were to characterize follicle growth and associated changes in systemic concentrations of gonadotropins and estradiol at 8-h ...

Follicular dynamics, repeatability and predictability of follicular recruitment in cows undergoing repeated follicular puncture

Theriogenology, 1997
The aim of our study was to characterize follicular recruitment and growth in response to the repeated removal of follicles. All tertiary follicles (> 2 mm of diameter) in the ovaries of 10 non-lactating Holstein Friesian cows were punctured at midcycle (Day 0) by means of an ultrasound-guided needle. Puncture sessions were scheduled twice weekly at 3-

Follicular dynamics in the polycystic ovary syndrome

Molecular and Cellular Endocrinology, 2000
Anovulation in women with polycystic ovary syndrome (PCOS) is characterised by arrested growth of antral follicles. A relative lack of FSH may contribute to the persistence of anovulation but is unlikely, by itself, to be a major cause of it. Granulosa cells from anovulatory women with polycystic ovaries hypersecrete oestradiol, compared with size ...

An Analysis of Follicular Punches, Mechanics, and Dynamics in Follicular Unit Extraction

Facial Plastic Surgery Clinics of North America, 2013
Success in follicular unit extraction requires an understanding of forces, fluid dynamics, instrumentation, and individual patient variation. Sharp punches require a lower axial and tangential force to dissect follicular groups. The angle of hair emergence and the size of a punch influence the wound size and the depth of an incision.
