Abstract
Background/Introduction
Although second-generation drug eluting stent (DES) employing biodurable polymer drastically shortened the duration of dual antiplatelet therapy (DAPT), previous reports raised concerns that switching from DAPT to single antiplatelet therapy increased rates of subsequent stent thrombosis with time. Third-generation DES employing bioabsorbable polymer has been introduced so as not to hinder the healing process of the vessel wall, however, at present, both DES with bioabsorbable polymer and those with biodurable polymer are used in parallel. It means there is no conclusive evidence regarding pros and cons of these two types of polymers.
Purpose
This study aims to clarify how bioabsorbable polymer and biodurable polymer act on the human coronary artery by observing neointimal stent coverage (NIC) and in-stent thrombus by comparing the third-generation DES with bioabsorbable-polymer cobalt-platinum everolimus-eluting stent (BP CoPt-EES), and the second-generation DES with biodurable-polymer cobalt-chromium everolimus-eluting stent (DP CoCr-EES).
Methods
This is a multicenter observational study including 11 hospitals. We investigated 70 stents (BP CoPt-EES: 40, DP CoCr-EES: 30) of 60 cases, who underwent stent implantation followed by simultaneous observation by coronary angiography, IVUS and angioscopy within 6 to 12 months. For angioscopy, we used a recently available, high-resolution angioscope with a pixel count of 9,000 which realized both stent coverage analysis and planar thrombus detection precisely. Neointimal stent coverage was graded from G0: non coverage to G3: full coverage, and heterogeneity value of neointima was measured as the difference between maximum and minimum NIC grade.
Results
A strong relationship was observed between NIC grade and in-stent thrombus in all stents (p=0.0011), and between the heterogeneity value and stent thrombus (p=0.012). There was no statistical difference in NIC grade between BP CoPt-EES vs. DP CoCr-EES; grade 0: 0 (0.0%) vs. 2 (6.7%), grade 1: 13 (32.5%) vs. 11 (36.7%), grade 2: 6 (15.0%) vs. 6 (20.0%), grade 3: 21 (52.5%) vs. 11 (36.7%), p=0.17) and neither in the heterogeneity value of neointima (p=0.49). The ratio of stent thrombus did not reach statistical difference; 16 (40.0%) in BP CoPt-EES vs. 17 (56.7%) in DP CoCr-EES (p=0.23).
Conclusion
The existence of stent thrombus was associated with the neointimal stent coverage. There was no significant difference both in neointimal stent coverage and stent thrombus between bioabsorbable polymer cobalt-platinum EES and biodurable polymer cobalt-chromium EES after 6 to 12 months following stent deployment.

Abstract
Abstract
Background
The use of intravascular ultrasound (IVUS) promotes better clinical outcomes for intervention in complex lesions. However, the data demonstrating whether use of IVUS improves primary patency following stenting for aorto-iliac lesions in patients with peripheral artery disease (PAD) are limited.
Purpose
The purpose of the current study was to investigate the impact of IVUS use on primary patency 12 months after stent implantation for aorto-iliac lesions.
Methods
We analyzed a clinical database of the OMOTENASHI registry (Observational prospective Multicenter registry study on Outcomes of peripheral arTErial disease patieNts treated by AngioplaSty tHerapy in aortoIliac artery), registering symptomatic PAD patients (Rutherford category 2, 3, or 4) undergoing endovascular therapy for aorto-iliac lesions between January 2014 and April 2016 in Japan. The current study analyzed 803 patients who underwent self-expandable stent implantation at 61 centers with the institutional volume known. The primary endpoint was 12-month restenosis, defined as ≥50% stenosis on computed tomography or angiography, or a peak systolic velocity ratio ≥2.5 on duplex ultrasound. When treatment strategies, endovascular procedures and clinical outcomes were compared between the patients treated with IVUS use and those treated without IVUS use, the propensity score matching was performed to minimize the inter-group difference in baseline characteristics.
Results
A total of 545 patients (67.9%) underwent IVUS-supported stent implantation. Patients treated with IVUS use had a lower prevalence of regular dialysis, whereas they had a higher prevalence of TASC II class D and chronic total occlusion. In patients treated with IVUS use, carbon dioxide contrast agent were more often used, and 0.035-inch guidewire was less frequently selected. Implanted stents in these patients were longer and smaller in diameter. The propensity score matching extracted 138 pairs, with no remarkable intergroup difference in baseline characteristics. Procedure time ≤1 hour was less frequent in patients treated with IVUS use; their radiation time was longer. Endovascular strategies, as well as postoperative medication were not significantly different between patients with and without IVUS use. The 12-month restenosis risk was not significantly different between patients with and without IVUS use (10.2% [6.9 to 14.9%] versus 10.3% [5.4 to 18.6%], P=0.99).
Conclusion
IVUS use in aorto-iliac stenting for patients with PAD was not associated with primary patency at 12 months.

Abstract
PURPOSE To review the outcome of bone-peg grafting for osteochondritis dissecans (OCD) grade II lesions of the humeral capitellum. METHODS Records of 10 male adolescent baseball players aged 10 to 15 (mean, 12.3) years who underwent bone-peg grafting for OCD grade II lesions of the humeral capitellum of the dominant arm were reviewed. The mean time from symptom onset to presentation was 11 (range, 1-36) months. The mean duration of conservative treatment was 5 (range, 1-25) months. The mean time from symptom onset to surgery was 17 (range, 3-39) months; it was >6 months in 6 patients. The mean size of the lesions was 13x14 mm. Patients were assessed for elbow pain, range of elbow and forearm motion, Timmerman- Andrews elbow score, return to sports activity level, and radiographic evidence of healing, osteoarthritic changes, and radial head hypertrophy. RESULTS The mean follow-up period was 25 (range, 10-52) months. Postoperatively, elbow pain was absent in 6, mild in 2, and moderate in 2 patients. The mean range of elbow motion changed from 136º to 139° (p=0.80). The mean Timmerman-Andrews elbow score improved from 163 to 189 (p=0.014); it was excellent in 7, good in 2, and fair in one patient. The mean extent of lesion healing was 71% (range, 33-100%). Five patients achieved complete healing after a mean of 5.2 (range, 5-6) months and returned to sports at a competitive level. The other 5 achieved partial healing of 33 to 56% (mean, 41%) that occurred laterally but not medially. Two of them returned to sports at a competitive level: one changed the throwing side and another had radial head hypertrophy. The remaining 3 underwent arthroscopic debridement of the unhealed lesion at 5, 10, and 15 months. One patient developed secondary osteoarthritis and further underwent costal osteochondral autografting 10 months later. None of the 5 patients with partial healing versus 4 of the 5 patients with complete healing underwent surgery within 6 months of symptom onset. All 3 patients with a dot at the interface versus 2 of the 6 patients with a line at the interface between the fragment and the lesion on MRI had complete healing. CONCLUSION Bone-peg grafting is a viable option for OCD grade II lesions of the humeral capitellum when performed within 6 months of symptom onset and when the interface between the fragment and the lesion appears as a dot (rather than a line) on MRI.

Abstract
Abstract The purpose of this study was to demonstrate the radiological features of long bones in synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome and to correlate these with the clinical findings. Eleven long bone lesions in seven cases of SAPHO syndrome were examined. The patients ranged in age from 6 to 63 years, with a mean of 47 years. In all seven cases, radiography, (99m)technetium bone scintigraphy, CT scan, and magnetic resonance imaging (MRI) were performed. In six of the cases, bone biopsy and bone culture were carried out for 7 long bones. Seven of the involved lesions were from the shaft of the femur, one each was from the neck and the shaft of the humerus, and one was from the proximal tibia. These lesions showed radiologically hyperostosis, osteolysis, and bone infarction-like lesion. Osteolysis was occasionally accompanied by sclerotic change. Hyperostosis usually showed diaphyseal involvement, presenting low signal intensity on T1- and T2-weighted MR images. Histologically, these findings corresponded to massive bone necrosis, new bone formation, fibrosis, or a mixture of these associated with mild inflammatory cell infiltration. Osteolysis involved dyaphysis, metaphysis, or epiphysis associated with arthritis, and presented low signal intensity on T1-weighted images, nonhomogeneous signal intensity lower than fat on T2-weighted images, and high signal intensity on fat suppression images. These findings corresponded to fibrosis, granulation, and inflammatory cell infiltration with lymphocyte aggregation. Bone infarction-like lesion was observed in the shaft or neck of the femur and the humerus and accompanied by calcification and cystic change. Bone cultures were negative in all cases in which bone biopsy was performed. Although hyperostosis is thought to be a characteristic bone lesion in SAPHO syndrome, the long bone lesion can occasionally show not only hyperostosis but also osteolytsis and bone infarction-like lesions.

Abstract
OBJECTIVE To identify anatomical factors associated with major adverse limb events (MALE) after angioplasty as the basis for a novel morphology-driven classification of infrapopliteal lesions. DESIGN Retrospective-multicenter study. MATERIALS AND METHODS Between March 2004 and October 2010, 1057 limbs from 884 patients with CLI due to isolated infrapopliteal lesions were studied. Freedom-from MALE, defined as major amputation or any reintervention, was assessed out to 2 years by the Kaplan-Meier methods. Anatomical predictors and risk stratification for MALE were analyzed by multivariate analysis. RESULTS Freedom-from MALE was 47 ± 1% at 2 years. Lesion calcification, target vessel diameter<3.0 mm, lesion length>300 mm and no below-the-ankle (BA) run-off were positively associated with MALE by multivariate-analysis. The total number of risk factors was used to calculate the risk score for each limbs for subsequent categorization into 3 groups with 0 or 1 (low-risk), 2 (moderate-risk) and 3 or 4 (high-risk) factors. Freedom-from MALE at 2 year-rates was 59% in low-risk, 46% in moderate-risk, and 29% in high-risk, respectively. CONCLUSION Target vessel diameter <3.0 mm, lesion calcification, lesion length > 300 mm and no-BA run-off were associated with MALE after infrapopliteal angioplasty. Risk stratification based on these predictors allows estimation of future incidence of MALE in CLI with isolated infrapopliteal lesions.

Abstract
BACKGROUND Cathepsin K (CTSK), a cysteine protease with strong collagenolytic and elastolytic properties involved in extracellular matrix turnover, may be produced by neoplastic cells as well as stromal macrophages and fibroblasts. Its expression is suggested as associated with increased invasive and metastatic potential. OBJECTIVES The aim of this study is to examine stromal expression of cathepsin K in skin tumors. METHODS A series of 13 normal skin and 109 skin tumours, including 51 benign and 58 malignant epidermal tumours were tested for CTSK and Ki-67 expression by immunohistochemical analysis. RESULTS Stromal CTSK expression and the tumoral Ki-67 labelling index were significantly higher in invasive squamous cell carcinoma (SCC) than in other epidermal tumours. CONCLUSION Cathepsin K-positive stromal fibroblasts may play a crucial role in SCC progression by promoting extracellular matrix degradation, thereby facilitating SCC growth and invasion into surrounding tissue and vasculature. CTSK inhibitors may be a potential novel therapeutic option to decrease SCC progression.

Abstract
Pustulosis palmaris et plantaris (PPP) is a tonsil-related disease; tonsillectomy is somewhat effective in treating the condition. However, the aetiological association between the tonsils and PPP has not yet been elucidated fully. Recently, some chemokines and chemokine receptors, including CC chemokine receptor (CCR) 4, CCR6 and CX chemokine receptor (CXCR) 3, have been reported to play important roles in the development of psoriasis, a disease related closely to PPP. In this study, we found that CCR6 expression on both tonsillar and peripheral blood T cells was up-regulated more intensively in PPP patients than in non-PPP patients (P < 0.001 for both), but CCR4 and CXCR3 expressions were not. In vitro stimulation with alpha-streptococcal antigen enhanced CCR6 expression significantly on tonsillar T cells in PPP patients (P < 0.05), but this was not observed in non-PPP patients. The chemotactic response of tonsillar T cells to the CCR6 ligand CC chemokine ligand (CCL) 20 was significantly higher in PPP patients than in non-PPP patients (P < 0.05). The percentage of CCR6-positive peripheral blood T cells decreased after tonsillectomy in PPP patients (P < 0.01); this decrease correlated with an improvement of skin lesions (P < 0.05, r = -0.63). The numbers of CCR6-positive cells and the expression of CCL20 were increased significantly in pathological lesions compared with non-pathological lesions in PPP skin (P < 0.01, P < 0.05 respectively). These results suggest that a novel immune response to alpha-streptococci may enhance CCR6 expression on T cells in tonsils and that CCR6-positive T cells may move to peripheral blood circulation, resulting in recruitment to target skin lesions expressing CCL20 in PPP patients. This may be one of the key roles in pathogenesis of the tonsil-related disease PPP.

Abstract
BACKGROUND The enzyme mammalian target of rapamycin (mTOR) integrates many different cellular signals to control cell growth and proliferation, protein synthesis and breakdown, and other processes. Dysregulation of mTOR is implicated in a range of human diseases, including cancers and cardiovascular disorders. To date, there has been no report on the expression of protein kinase B (AKT)/mTOR cell signalling in epidermal tumours. OBJECTIVES This study was designed to investigate the activation of the mTOR signalling pathway in epidermal tumours and to correlate this with cyclin-dependent kinase 2 (CDK2) expression. METHODS Immunohistological staining was performed with phosphorylated (p-) AKT, p-mTOR, p-4E-binding protein 1 (p-4EBP1), p-ribosomal protein S6 (p-S6), p-p70 ribosomal protein S6 kinase 1 (p-p70S6K1) and CDK2 in 15 cases each of seborrhoeic keratosis, actinic keratosis, keratoacanthoma and Bowen's disease (BD), and 25 cases of squamous cell carcinoma (SCC). Fifteen normal skin (NS) samples served as control. RESULTS Among 85 tumours, 40 (47%) were positive for p-AKT, 31 (36%) for p-mTOR, 44 (52%) for p-4EBP1, 38 (45%) for p-S6, and 39 (46%) for p-p70S6K1. CDK2 immunostaining was positive in all cases of SCC and BD, and in 67% of benign tumours. All of these markers were stained much more frequently in malignant tumours than in benign tumours or NS. p-AKT, p-mTOR, p-4EBP1, p-p70S6K1 and p-S6 each showed high correlation with CDK2. CONCLUSIONS Constitutive activation of the AKT/mTOR pathway was frequent in epidermal tumours, especially in malignant tumours. Activation was highly correlated with CDK2 expression, suggesting that the AKT/mTOR pathway may induce the malignant transition through CDK2 in epidermal tumours.

Abstract
BACKGROUND Cytokeratin 19 (CK19) has been considered to be a putative marker for epidermal stem cells in the hair follicle bulge. Cumulative reports have shown that epidermal stem cells play an important role in skin carcinogenesis. However, to date there has been no report on the clinical alteration of the stem cells in squamous cell carcinoma (SCC). OBJECTIVES To investigate alteration of the stem cells and proliferating cells and to assess their relationship and potential contribution to SCC. METHODS Thirty paraffin-embedded neoplastic skin lesions, consisting of 10 cases each of actinic keratosis (AK), Bowen disease (BD) and SCC, were examined immunohistologically for CK19 and Ki-67. RESULTS Positive reactivity for CK19 was seen in 30% of AK, 50% of BD and 80% of SCC lesions. There was significantly higher expression levels of CK19 in SCC than in AK and BD (P < 0.05). In addition, BD lesions harboured a significantly higher number of CK19-positive cells than did AK lesions (P < 0.05). There were significant differences in Ki-67 labelling indices between AK and BD and between AK and SCC (P < 0.001), but not between BD and SCC (P > 0.05). Furthermore, a serial section comparison study showed that there was a minor population of cells co-expressing CK19 and Ki-67 in a subset of the tumour cells of SCC samples. The percentage of CK19+ cells significantly correlated with that of Ki67+ cells in all examined neoplastic skin lesions. CONCLUSIONS These results suggest that CK19 expression may be associated with the retention of stem cell characteristics or a state that is uncommitted to terminal squamous differentiation.

Abstract
IgA nephropathy (IgAN), the most common form of primary glomerulonephritis, is recognized as a disease that often becomes worse during acute tonsillitis. Although many reports have shown that tonsillectomy is an effective treatment for IgAN patients, the immunological evidence has not yet been investigated fully. In this study, we compared the expression of T cell receptor (TCR) V beta families in tonsillar T cells of IgAN patients to those of non-IgAN patients. The reverse transcription-polymerase chain reaction (RT-PCR) and flow cytometric analyses showed that the TCR V beta 6 was used more frequently in tonsillar T cells of IgAN patients than in those of non-IgAN patients (P < 0.01 each). Similarly, the proportions of TCR V beta 6-positive cells in peripheral blood T cells were significantly higher in IgAN patients than in non-IgAN patients (P < 0.05). After tonsillectomy, the proportions decreased in IgAN patients (P < 0.05), but did not in non-IgAN patients. Furthermore, in vitro stimulation with Haemophilus parainfluenzae antigen, which is reported to deposit in the glomerular mesangium of IgAN, enhanced expression of TCR V beta 6 in tonsillar T cells from both IgAN and non-IgAN patients. These results suggest that TCR V beta 6-positive tonsillar T cells might be activated by H. parainfluenzae, move into the kidney through blood circulation and induce glomerulonephritis.

Abstract
OBJECTIVE To show the phenotypic characteristics of the knee joints in brachypodism mice (bp mice), which carry a functional null mutation of the growth differentiation factor 5 (GDF5) gene, we investigated the adult and embryonic bp mice. METHOD Radiographic and macroscopic examinations of the knee joint of adult bp mice were performed. A histological examination of the knee joint of bp mice from E12.5 to E18.5 was also performed. RESULTS Radiographic and macroscopic examinations of the adult bp mice showed anterior dislocation, hypoplastic condyles, and absence of the intra-articular ligaments. Safranin O staining of knee joints of the embryonic bp mice showed severe hypoplasty of the chondroepiphyses and intra-articular ligaments at E16.5. There was no difference in the number and location of 5-bromo-2'-deoxyuridine (BrdU)-positive cells between wild-type and bp mice through E12.5 to E14.5. A terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling (TUNEL) study showed excessive cell death of mesenchymal cells of the future knee joint in bp mice at E12.5 and E13.5. CONCLUSION bp mice exhibit developmental failure of the condyles and intra-articular ligament of the knee joints.

Abstract
The EBV carrier state is almost general in men. The virus induces B lymphocyte proliferation in vitro, but this is counteracted in vivo by the immune response. Therefore, EBV-induced malignancies occur only when the immune response is impaired, e.g. in transplant recipients. The versatility of the viral gene expression strategy secures the consistent maintainance of the virus in healthy individuals. The viral proteins required for transformation render the cell immunogenic. Expression of the transforming genes leads to rejection, but these genes are not required for the maintenance of the viral genome. EBV is an important contributor for malignant transformation, even when it does not directly induce cell proliferation. Several mechanisms have been unravelled in EBV-associated tumors whereby the virus may modify the cellular phenotype and may influence the interaction of tumor cells with their microenvironment. The virus carrier state can lead to the evasion of apoptosis and can intensify the response to growth promoting signals, too.

Abstract
To cover a large soft-tissue defect and to reconstruct the shoulder contour after forequarter amputation, we used an osteomyocutaneous free flap incorporating an elbow joint from the amputated extremity in two patients. These flaps were well vascularised and reliable. They provided excellent coverage of large soft-tissue defects and they maintained shoulder contours. This procedure is useful for reconstruction after extended forequarter amputation and chest wall resection.

Abstract
SAP is an adaptor molecule with one SH2 domain and it is expressed in activated T and NK cells, where it is required for the appropriate signaling from the SLAM family of surface receptors. Deleted or mutated SAP genes that encode functionally defective protein are associated with the X-linked lymphoproliferative disease (XLP). This primary immunodeficiency is characterized by extreme sensitivity to Epstein-Barr virus (EBV) infection, dysgammaglobulinemia and a high rate of lymphoma development. The vigorous T- and B-cell proliferation that follows EBV infection and the high incidence of lymphomas (30%) in XLP patients might reflect functional defects in cell cycle and/ or apoptosis control. Our experiments show that SAP is a target of p53. In Burkitt lymphoma (BL) lines transfected with a temperatur-sensitive (ts) p53, SAP mRNA and protein expression was dependent on wild-type (wt) p53. Activation of endogenous wt p53 in BLs and lymphoblastoid cell lines led to the induction of SAP and this was inhibited by the specific p53 inhibitor pifithrin-alpha. Cell lines that carried mutant p53 did not express SAP under similar conditions. Moreover, we have shown binding of wt p53 to the promoter region of SAP by ChIP assay. Our results suggest that SAP contributes to the execution of some p53 functions.

Abstract
A 29-year-old woman with primary pulmonary hypertension presented with recurrent hemoptysis. Contrast-enhanced CT of the chest demonstrated the enhanced mass surrounded by consolidation related to parenchymal hemorrhage. Pulmonary angiography suggested that the mass was a pulmonary artery false aneurysm. After a microcatheter was superselectively inserted into the parent artery of the false aneurysm, the false aneurysm was successfully treated by transcatheter embolization with coils. Her hemoptysis has never recurred.

Abstract
Treatment outcomes of tonsillectomy were studied in 7 Japanese patients with psoriasis--3 males and 4 females aged 9 to 46 years (median: 23 years)--followed up 2 to 9 years after tonsillectomy. All skin lesions disappeared in 3 patients, 80% of those in 2, and no change in the remaining 2 during follow-up. Of 5 in whom skin lesions improved, 4 were females and had a history of tonsillitis making skin lesions worse. In quantitative immunohistologic analysis on tonsillar tissues by CD20 and anti-ssDNA antibodies, areas of T cell-nodules were significantly expanded, but those of the B-lymphoid follicles were smaller, and the number of apoptotic cells increased in tonsils from patients with psoriasis and PPP compared to those with recurrent tonsillitis. The area of T cell-nodules and the number of apoptosis cells were significantly larger in tonsils from 4 patients with complete recovery after tonsillectomy compared to the remaining 9 without complete recovery. This suggests that histologic evaluation may be helpful in estimating the effectiveness of tonsillectomy.

Abstract
Y-box binding proteins, a large family of proteins, are involved in a variety of functions. The present study describes the expression of YB2, a rat Y-box binding protein, and/or RYB-a, an alternatively spliced product of the YB2 gene during spermatogenesis. YB2/RYB-a is thought to be the rat orthologue of mouse Y-box protein 3 (MSY3). An antibody which recognizes YB2/RYB-a was developed and applied in an immunochemical study of rat and mouse testes. We also carried out an in-situ hybridization study and Northern blot analysis of YB2/RYB-a and protamine 2 mRNA expression. Both YB2/RYB-a mRNA and the proteins appeared in prepubertal mouse testes, prior to the expression of the mouse protamine 2 mRNA. The mRNA and protein were present at high levels in spermatocytes, decreased in round to elongated spermatids, and were absent in spermatozoa. Since the protamine 2 mRNA was present at high levels in round and elongating spermatids, the proposed function of the YB2/RYB-a protein as a translational repressor of the mRNA was supported in mouse. The level and localization of YB2/RYB-a mRNA and protein expression in the rat testis was comparable to that in mouse testis, although rat testis is known to express a very low level of protamine 2, but is also likely to affect the expression of other proteins (including protamine 1) during spermatogenesis.

Abstract
During plastid division, two structures have been detected at the division site in separate analyses. The plastid-dividing ring can be detected by transmission electron microscopy as two (or three) electron-dense rings: an outer ring on the cytosolic face of the outer envelope, occasionally a middle ring in the intermembrane space, and an inner ring on the stromal face of the inner envelope. The FtsZ ring, which plays a central role in bacterial division, also is involved in plastid division and is believed to have descended to plastids from cyanobacterial endosymbiosis. The relationship between the two structures is not known, although there is discussion regarding whether they are identical. Biochemical and immunocytochemical investigations, using synchronized chloroplasts of the red alga Cyanidioschyzon merolae, showed that the plastid FtsZ ring is distinct and separable from the plastid-dividing ring. The FtsZ ring localizes in stroma and faces the inner plastid-dividing ring at the far side from the inner envelope. The FtsZ ring and the inner and outer plastid-dividing rings form in that order before plastid division. The FtsZ ring disappears at the late stage of constriction before dissociation of the plastid-dividing ring, when the constriction is still in progress. Our results suggest that the FtsZ ring;-based system, which originated from a plastid ancestor, cyanobacteria, and the plastid-dividing ring;-based system, which probably originated from host eukaryotic cells, form a complex and are involved in plastid division by distinct modes.

Abstract
The role of Candida albicans yeast-to-hyphae transition in interleukin-12 (IL-12) production by monocytes was investigated. Germinating C. albicans not only failed to induce IL-12 p70 but also suppressed IL-12 production induced by heat-killed C. albicans. Comparison of the abilities of germinating C. albicans and agerminating mutants to inhibit IL-12 production showed that germination of C. albicans plays a critical role in the inhibition of IL-12 production.
