The distribution of the lysosomal enzymes cathepsin B, lysozyme, ehymotrypsin, and neutrophil elastase was examined in eccrine, apocrine, and sebaceous glands using a postembedding immunogold labeling procedure. Various amounts of cathepsin B were detected in all glands. Lysozyme, however, was detected in apocrine glands only. The other two lysosomal enzymes Were not detectable immunologically. In apocrine and eccrine glands, anti‐cathepsin B antibody labeled all secretory granules. In… 
Immunocytochemical and immunoelectron microscopic demonstration of cathepsin B in human malignant melanoma
TLDR
Immunological staining with anticathepsin B antibody indicates that the subcellular distribution of cathepsIn B in tumour cell lines differs from that in normal liver.
In Silico, In Vitro, and Clinical Investigations of Cathepsin B and Stefin A mRNA Expression and a Correlation Analysis in Kidney Cancer
TLDR
The data strongly indicated that CtsB and StfA expression play an important role in R CC development by mutually stimulating their expression in RCC progression.
Cathepsin B as a cancer target
TLDR
It is not clear whether global suppression of cathepsin B activity or expression would produce unintended effects or cause the activation or suppression of unwanted pathways, so a combination of targeting cathePSin B with other relevant oncogenic molecules has significant therapeutic potential.
Techniques in immuno‐electron microscopy
TLDR
Normal skin was cryoprotected by submerging it in a mixture of 30% dimethylformamide (DMF) in PBS or RPMI and frozen in liquid propane gas and the overall morphology was better in Epon‐embedded material than in K4M‐embedclecl material.
New applications of electron microscopy techniques in dermatopathology
TLDR
Refinements in the preparative procedures have made easier the immunolocalization of antigens both in chemically‐fixed and frozen unfixed tissues, embedded in plastic and sectioned.
For debate Immunological functions of the human prepuce
The demonisation of the human male prepuce has been an unscientific process, even though some research, on the surface, might seem to support it. In the late 19th century, when male circumcision came
Immunological functions of the human prepuce.
TLDR
A review of the scientific literature reveals that the actual eVect of circumcision is the destruction of the clinically demonstrated hygienic and immunological properties of the prepuce and intact penis.
Activity, expression, and transcription rate of the cathepsins B, D, H, and L in cutaneous malignant melanoma
TLDR
Increased activity of the protease cathepsin B has been demonstrated in many tumor cells and its correlation with metastatic potential of melanoma has been well established.
Is aerobic preputial flora age dependent?
TLDR
Preputial cultures change with age in uncircumcised boys, and this change may be related to the development of immune status, to histological or anatomical changes in the prepuce, and/or to improved personal hygiene.

TLDR
The results suggest that cathepsins B, H, and L participate not only in degradation of thyroglobulin but in maturation of thyroid hormones, although it remains unknown whether all of them participate in the maturation process.

TLDR
Examination of sebaceous glands from adult rats by means of electron microscopy and combined cytochemistry produced convincing information implicating the smooth surfaced endoplasmic reticulum and the Golgi complex with the formation of lysosomes.
Immunoenzyme localization of cathepsins in the Golgi region of rat hepatocytes and renal tubule cells
TLDR
The results suggests that cathepsins are transported by vesicular system from the rER to lysosomes via Golgi apparatus and the small vesicle transport the proteinases from the ER to the Golgi cisternae and the large clathrin-coated vesicles from the Golginae to the lysoomes.

TLDR
The results suggest that cathepsin B plays a role in protein degradation in lysosomes of corticotrophs and melanotrophies and may indicate that the enzyme participates in the activation of secretory products.
Immunocytochemical localization of cathepsin H in rat kidney
TLDR
The results indicate that a main site for cathepsin H in rat kidney is the S1 segment of the proximal tubules, which is significantly low levels compared with other renal segments.

TLDR
The results suggest the possibility that processing of prorenin to renin occurs in immature granules of rat JG cells, and cathepsin B detected inJG cells may be a major candidate for the maturation of renin.

TLDR
Observations support an epithelial origin of cutaneous lysozyme and suggest a means of further characterization of the origin and/or differentiation of tumors of appendageal origin.

TLDR
The results suggest that co-localization of cathepsin B and ANP in secretory granules is compatible with the possibility that cathePSin B participates in the maturation process of ANP.

TLDR
The results indicate that in rat kidney the lysosomes of the S1 segment are a main location of cathepsin B, and the endocytotic apparatus including the apical vesicles, tubules, and vacuoles contains no cathePSin B.
