Teloptosis, a turning point in hair shedding biorhythms.

The timing regulation of the hair growth phases is quite complex. We name teloptosis the termination of the telogen phase with hair shedding. The initiation of the next anagen I phase is independent from teloptosis. Both events are triggered by distinct factors. Indeed, teloptosis is the result of the loss of adhesion between cells of the club hair and those of its epithelial envelope. Teloptosis synchronization is perceived as telogen effluvium, related or not to shortening of the anagen phase. Subtle changes leading to early or delayed teloptosis affect hair density. It is possible to distinguish two types of telogen hairs on a trichogram. Those with an epithelial sheath indicate strong binding, suggesting early telogen, whereas the absence of an epithelial sheath indicates loose binding, conveying teloptosis. Copyright 2001 S.

Fifty consecutive patients with stage IIIB-IV non-small cell lung cancer (NSCLC) received the ICE regimen at intermediate doses (ifosfamide 1 g/m2, carboplatin 120 mg/m2, etoposide 80 mg/m2, day 1 to 3, q.4 weeks, for a maximum of 6 cycles). Overall 2 complete response (CR) and 10 partial response (PR) (overall response, OR: 24%, 95% C.I. 14-37%) were observed. An additional 7 patients had stable disease (SD) lasting more than 6 months, therefore a clinical benefit (CR+PR+SD >6 mos) was achieved in 19 patients (38%). Median time-to-progression (TTP) was 7 months and median overall survival (OS) was 11 months; 1- and 2-year survival rates were 36% and 10%. The ICE regimen was well tolerated and devoid of any cardiac, hepatic or neurologic toxicity. Moderate nausea and vomiting were easily manageable, grade 2 alopecia was universal, while hematological toxicity was mild (grade 2 leuko- and thrombocytopenia). Due to its efficacy and safety profile, this 3-drug regimen can be considered for routine community use.

BACKGROUND: The control of human hair follicle growth and differentiation is dependent upon several well-identified factors, including androgens, cytokines, and growth factors. In humans, alopecia androgenetica is a common aging process thought to be regulated through complex genetic imbalances, which also involve several of these crucial identified factors (and probably others not yet characterized), alone or in combination. Among these factors, epidermal growth factor (EGF), as well as pro-inflammatory cytokines, play a pivotal role, as evidenced by their direct inhibitory effects on hair growth both in vitro and in vivo. Following such treatments, the in vitro growth of hair follicles was rapidly arrested and deleterious modifications of hair morphology were also observed. AIM: Because these cytokines act, at least partly, through the induction of matrix metalloproteinases (MMP), and because tissue remodeling occurs during the hair cycle, we attempted to identify and localize MMP in the human pilosebaceous unit. METHOD: We used zymography to observe human hair follicles in culture in vitro. RESULTS: We observed that human hair follicles in culture in vitro mainly and almost exclusively produce MMP-2 and MMP-9 gelatinolytic activities. Furthermore, after stimulation with EGF, tumor necrosis factor-alpha (TNF-alpha), or interleukin-1alpha (IL-1alpha), MMP-9 production was strongly increased. Using immunohistochemistry, we then precisely localized MMP-9 in the lower part of the inner root sheath (Henle's layer) of control human anagen hair follicles. CONCLUSIONS: Cytokine- and EGF-induced upregulation of MMP-9 in the lower epithelial compartment of the human hair bulb is a major mechanism through which hair follicle involution, observed in alopecia, may occur.
